From: Torsten Giebl Subject: ALLOCA Patch for SDL-1.2 Newsgroups: gmane.comp.lib.sdl Date: 2006-10-24 00:31:16 GMT 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 ). CU
