Hello !
As alloca.h is not available on CYGWIN and MinGW32
it should not be checked there or it should be checked
with -mno-cygwin using.
I am a total configure.in newbie, but i found the way
that things are handled in configure.in pretty bad for the
case CYGWIN with MinGW Mode or not.
Maybe this is not possible but i would like to
have a way to detect at the start for example CYGWIN
and then add. ask if configure was called with --enable-cygwin
for example. --enable-cygwin should be optional and disabled
by default as we want to have MinGW Mode by default.
Only if the user wants it he should be able to use it.
Then the whole configure.in would get add. questions
okay the system is CYGWIN with or without MinGW Mode.
The alloca.h thing for example is only
available under CYGWIN ( without MinGW Mode ).

122 Each licensee is addressed as "you". |
| 0 | 123 |
| 124 A "library" means a collection of software functions and/or data | |
| 125 prepared so as to be conveniently linked with application programs | |
| 126 (which use some of those functions and data) to form executables. | |
| 127 | |
| 128 The "Library", below, refers to any such software library or work | |
| 129 which has been distributed under these terms. A "work based on the | |
| 130 Library" means either the Library or any derivative work under | |
| 131 copyright law: that is to say, a work containing the Library or a | |
| 132 portion of it, either verbatim or with modifications and/or translated | |
| 133 straightforwardly into another language. (Hereinafter, translation is | |
| 134 included without limitation in the term "modification".) | |
| 135 | |
| 136 "Source code" for a work means the preferred form of the work for | |
| 137 making modifications to it. For a library, complete source code means | |
| 138 all the source code for all modules it contains, plus any associated | |
| 139 interface definition files, plus the scripts used to control compilation | |
| 140 and installation of the library. | |
| 141 | |
| 142 Activities other than copying, distribution and modification are not | |
| 143 covered by this License; they are outside its scope. The act of | |
| 144 running a program using the Library is not restricted, and output from | |
| 145 such a program is covered only if its contents constitute a work based | |
| 146 on the Library (independent of the use of the Library in a tool for | |
| 147 writing it). Whether that is true depends on what the Library does | |
| 148 and what the program that uses the Library does. | |
| 149 | |
| 150 1. You may copy and distribute verbatim copies of the Library's | |
| 151 complete source code as you receive it, in any medium, provided that | |
| 152 you conspicuously and appropriately publish on each copy an | |
| 153 appropriate copyright notice and disclaimer of warranty; keep intact | |
| 154 all the notices that refer to this License and to the absence of any | |
| 155 warranty; and distribute a copy of this License along with the | |
| 156 Library. | |
| 157 | |
| 158 You may charge a fee for the physical act of transferring a copy, | |
| 159 and you may at your option offer warranty protection in exchange for a | |
| 160 fee. | |
| 161 | |
| 162 2. You may modify your copy or copies of the Library or any portion | |
| 163 of it, thus forming a work based on the Library, and copy and | |
| 164 distribute such modifications or work under the terms of Section 1 | |
| 165 above, provided that you also meet all of these conditions: | |
| 166 | |
| 167 a) The modified work must itself be a software library. | |
| 168 | |
| 169 b) You must cause the files modified to carry prominent notices | |
| 170 stating that you changed the files and the date of any change. | |
| 171 | |
| 172 c) You must cause the whole of the work to be licensed at no | |
| 173 charge to all third parties under the terms of this License. | |
| 174 | |
| 175 d) If a facility in the modified Library refers to a function or a | |
| 176 table of data to be supplied by an application program that uses | |
| 177 the facility, other than as an argument passed when the facility | |
| 178 is invoked, then you must make a good faith effort to ensure that, | |
| 179 in the event an application does not supply such function or | |
| 180 table, the facility still operates, and performs whatever part of | |
| 181 its purpose remains meaningful. | |
| 182 | |
| 183 (For example, a function in a library to compute square roots has | |
| 184 a purpose that is entirely well-defined independent of the | |
| 185 application. Therefore, Subsection 2d requires that any | |
| 186 application-supplied function or table used by this function must | |
| 187 be optional: if the application does not supply it, the square | |
| 188 root function must still compute square roots.) | |
| 189 | |
| 190 These requirements apply to the modified work as a whole. If | |
| 191 identifiable sections of that work are not derived from the Library, | |
| 192 and can be reasonably considered independent and separate works in | |
| 193 themselves, then this License, and its terms, do not apply to those | |
| 194 sections when you distribute them as separate works. But when you | |
| 195 distribute the same sections as part of a whole which is a work based | |
| 196 on the Library, the distribution of the whole must be on the terms of | |
| 197 this License, whose permissions for other licensees extend to the | |
| 198 entire whole, and thus to each and every part regardless of who wrote | |
| 199 it. | |
| 200 | |
| 201 Thus, it is not the intent of this section to claim rights or contest | |
| 202 your rights to work written entirely by you; rather, the intent is to | |
| 203 exercise the right to control the distribution of derivative or | |
| 204 collective works based on the Library. | |
| 205 | |
| 206 In addition, mere aggregation of another work not based on the Library | |
| 207 with the Library (or with a work based on the Library) on a volume of | |
| 208 a storage or distribution medium does not bring the other work under | |
| 209 the scope of this License. | |
| 210 | |
| 211 3. You may opt to apply the terms of the ordinary GNU General Public | |
| 212 License instead of this License to a given copy of the Library. To do | |
| 213 this, you must alter all the notices that refer to this License, so | |
| 214 that they refer to the ordinary GNU General Public License, version 2, | |
| 215 instead of to this License. (If a newer version than version 2 of the | |
| 216 ordinary GNU General Public License has appeared, then you can specify | |
| 217 that version instead if you wish.) Do not make any other change in | |
| 218 these notices. | |
| 219 | |
| 220 Once this change is made in a given copy, it is irreversible for | |
| 221 that copy, so the ordinary GNU General Public License applies to all | |
| 222 subsequent copies and derivative works made from that copy. | |
| 223 | |
| 224 This option is useful when you wish to copy part of the code of | |
| 225 the Library into a program that is not a library. | |
| 226 | |
| 227 4. You may copy and distribute the Library (or a portion or | |
| 228 derivative of it, under Section 2) in object code or executable form | |
| 229 under the terms of Sections 1 and 2 above provided that you accompany | |
| 230 it with the complete corresponding machine-readable source code, which | |
| 231 must be distributed under the terms of Sections 1 and 2 above on a | |
| 232 medium customarily used for software interchange. | |
| 233 | |
| 234 If distribution of object code is made by offering access to copy | |
| 235 from a designated place, then offering equivalent access to copy the | |
| 236 source code from the same place satisfies the requirement to | |
| 237 distribute the source code, even though third parties are not | |
| 238 compelled to copy the source along with the object code. | |
| 239 | |
| 240 5. A program that contains no derivative of any portion of the | |
| 241 Library, but is designed to work with the Library by being compiled or | |
| 242 linked with it, is called a "work that uses the Library". Such a | |
| 243 work, in isolation, is not a derivative work of the Library, and | |
| 244 therefore falls outside the scope of this License. | |
| 245 | |
| 246 However, linking a "work that uses the Library" with the Library | |
| 247 creates an executable that is a derivative of the Library (because it | |
| 248 contains portions of the Library), rather than a "work that uses the | |
| 249 library". The executable is therefore covered by this License. | |
| 250 Section 6 states terms for distribution of such executables. | |
| 251 | |
| 252 When a "work that uses the Library" uses material from a header file | |
| 253 that is part of the Library, the object code for the work may be a | |
| 254 derivative work of the Library even though the source code is not. | |
| 255 Whether this is true is especially significant if the work can be | |
| 256 linked without the Library, or if the work is itself a library. The | |
| 257 threshold for this to be true is not precisely defined by law. | |
| 258 | |
| 259 If such an object file uses only numerical parameters, data | |
| 260 structure layouts and accessors, and small macros and small inline | |
| 261 functions (ten lines or less in length), then the use of the object | |
| 262 file is unrestricted, regardless of whether it is legally a derivative | |
| 263 work. (Executables containing this object code plus portions of the | |
| 264 Library will still fall under Section 6.) | |
| 265 | |
| 266 Otherwise, if the work is a derivative of the Library, you may | |
| 267 distribute the object code for the work under the terms of Section 6. | |
| 268 Any executables containing that work also fall under Section 6, | |
| 269 whether or not they are linked directly with the Library itself. | |
| 270 | |

271 6. As an exception to the Sections above, you may also combine or |
| 0 | 272 link a "work that uses the Library" with the Library to produce a |
| 273 work containing portions of the Library, and distribute that work | |
| 274 under terms of your choice, provided that the terms permit | |
| 275 modification of the work for the customer's own use and reverse | |
| 276 engineering for debugging such modifications. | |
| 277 | |
| 278 You must give prominent notice with each copy of the work that the | |
| 279 Library is used in it and that the Library and its use are covered by | |
| 280 this License. You must supply a copy of this License. If the work | |
| 281 during execution displays copyright notices, you must include the | |
| 282 copyright notice for the Library among them, as well as a reference | |
| 283 directing the user to the copy of this License. Also, you must do one | |
| 284 of these things: | |
| 285 | |
| 286 a) Accompany the work with the complete corresponding | |
| 287 machine-readable source code for the Library including whatever | |
| 288 changes were used in the work (which must be distributed under | |
| 289 Sections 1 and 2 above); and, if the work is an executable linked | |
| 290 with the Library, with the complete machine-readable "work that | |
| 291 uses the Library", as object code and/or source code, so that the | |
| 292 user can modify the Library and then relink to produce a modified | |
| 293 executable containing the modified Library. (It is understood | |
| 294 that the user who changes the contents of definitions files in the | |
| 295 Library will not necessarily be able to recompile the application | |
| 296 to use the modified definitions.) | |

322 normally distributed (in either source or binary form) with the major |
| 0 | 323 components (compiler, kernel, and so on) of the operating system on |
| 324 which the executable runs, unless that component itself accompanies | |
| 325 the executable. | |
| 326 | |
| 327 It may happen that this requirement contradicts the license | |
| 328 restrictions of other proprietary libraries that do not normally | |
| 329 accompany the operating system. Such a contradiction means you cannot | |
| 330 use both them and the Library together in an executable that you | |
| 331 distribute. | |
| 332 | |
| 333 7. You may place library facilities that are a work based on the | |
| 334 Library side-by-side in a single library together with other library | |
| 335 facilities not covered by this License, and distribute such a combined | |
| 336 library, provided that the separate distribution of the work based on | |
| 337 the Library and of the other library facilities is otherwise | |
| 338 permitted, and provided that you do these two things: | |
| 339 | |
| 340 a) Accompany the combined library with a copy of the same work | |
| 341 based on the Library, uncombined with any other library | |
| 342 facilities. This must be distributed under the terms of the | |
| 343 Sections above. | |
| 344 | |
| 345 b) Give prominent notice with the combined library of the fact | |
| 346 that part of it is a work based on the Library, and explaining | |
| 347 where to find the accompanying uncombined form of the same work. | |
| 348 | |
| 349 8. You may not copy, modify, sublicense, link with, or distribute | |
| 350 the Library except as expressly provided under this License. Any | |
| 351 attempt otherwise to copy, modify, sublicense, link with, or | |
| 352 distribute the Library is void, and will automatically terminate your | |
| 353 rights under this License. However, parties who have received copies, | |
| 354 or rights, from you under this License will not have their licenses | |
| 355 terminated so long as such parties remain in full compliance. | |
| 356 | |
| 357 9. You are not required to accept this License, since you have not | |
| 358 signed it. However, nothing else grants you permission to modify or | |
| 359 distribute the Library or its derivative works. These actions are | |
| 360 prohibited by law if you do not accept this License. Therefore, by | |
| 361 modifying or distributing the Library (or any work based on the | |
| 362 Library), you indicate your acceptance of this License to do so, and | |
| 363 all its terms and conditions for copying, distributing or modifying | |
| 364 the Library or works based on it. | |
| 365 | |
| 366 10. Each time you redistribute the Library (or any work based on the | |
| 367 Library), the recipient automatically receives a license from the | |
| 368 original licensor to copy, distribute, link with or modify the Library | |
| 369 subject to these terms and conditions. You may not impose any further | |
| 370 restrictions on the recipients' exercise of the rights granted herein. | |

371 You are not responsible for enforcing compliance by third parties with |
| 0 | 372 this License. |
| 373 | |
| 374 11. If, as a consequence of a court judgment or allegation of patent | |
| 375 infringement or for any other reason (not limited to patent issues), | |
| 376 conditions are imposed on you (whether by court order, agreement or | |
| 377 otherwise) that contradict the conditions of this License, they do not | |
| 378 excuse you from the conditions of this License. If you cannot | |
| 379 distribute so as to satisfy simultaneously your obligations under this | |
| 380 License and any other pertinent obligations, then as a consequence you | |
| 381 may not distribute the Library at all. For example, if a patent | |
| 382 license would not permit royalty-free redistribution of the Library by | |
| 383 all those who receive copies directly or indirectly through you, then | |
| 384 the only way you could satisfy both it and this License would be to | |
| 385 refrain entirely from distribution of the Library. | |

| 387 If any portion of this section is held invalid or unenforceable under any | |
| 388 particular circumstance, the balance of the section is intended to apply, | |

| 390 | |
| 391 It is not the purpose of this section to induce you to infringe any | |
| 392 patents or other property right claims or to contest validity of any | |
| 393 such claims; this section has the sole purpose of protecting the | |
| 394 integrity of the free software distribution system which is | |
| 395 implemented by public license practices. Many people have made | |
| 396 generous contributions to the wide range of software distributed | |
| 397 through that system in reliance on consistent application of that | |
| 398 system; it is up to the author/donor to decide if he or she is willing | |
| 399 to distribute software through any other system and a licensee cannot | |
| 400 impose that choice. | |
| 401 | |
| 402 This section is intended to make thoroughly clear what is believed to | |
| 403 be a consequence of the rest of this License. | |
| 404 | |
| 405 12. If the distribution and/or use of the Library is restricted in | |
| 406 certain countries either by patents or by copyrighted interfaces, the | |
| 407 original copyright holder who places the Library under this License may add | |
| 408 an explicit geographical distribution limitation excluding those countries, | |
| 409 so that distribution is permitted only in or among countries not thus | |
| 410 excluded. In such case, this License incorporates the limitation as if | |
| 411 written in the body of this License. | |

| 416 but may differ in detail to address new problems or concerns. | |
| 417 | |
| 418 Each version is given a distinguishing version number. If the Library | |
| 419 specifies a version number of this License which applies to it and | |
| 420 "any later version", you have the option of following the terms and | |
| 421 conditions either of that version or of any later version published by | |
| 422 the Free Software Foundation. If the Library does not specify a | |
| 423 license version number, you may choose any version ever published by | |
| 424 the Free Software Foundation. | |
| 425 | |
| 426 14. If you wish to incorporate parts of the Library into other free | |

| 429 copyrighted by the Free Software Foundation, write to the Free | |
| 430 Software Foundation; we sometimes make exceptions for this. Our | |
| 431 decision will be guided by the two goals of preserving the free status | |
