Fixed bug #176
[I'm fixing this for the public headers, but I'm not going to bother for the SDL library code (yet)]
To clarify: Normaly, GCC (or, to be precise, the preprocessor) will ignore
this, and compile the code happily. However, one can specify -Wundef to get a
warning about this.
One can probably argue whether to consider this a bug or not; but I think that
(a) from a semantic point of view, using "#if FOO" when FOO is not defined is
strange, and (b) since it is possible to trigger a warning about this, and a
trivial fix exists, it should be corrected.
I can think of two alternative patches, BTW:
1) Simply use #define HAVE_FOO 0, instead of not defining HAVE_FOO at all
2) Change
#if HAVE_FOO
to
#if HAVE_FOO+0
which always does the right thing.
But I think I still prefer the attached patch :-).

| 24 This library is distributed under GNU LGPL version 2, which can be | |
| 25 found in the file "COPYING". This license allows you to use SDL | |
| 26 freely in commercial programs as long as you link with the dynamic | |
| 27 library. | |
| 28 | |
| 29 The best way to learn how to use SDL is to check out the header files in | |
| 30 the "include" subdirectory and the programs in the "test" subdirectory. | |
| 31 The header files and test programs are well commented and always up to date. | |
| 32 More documentation is available in HTML format in "./docs/index.html" | |
| 33 | |
| 34 The test programs in the "test" subdirectory are in the public domain. | |
