Sigh, this seems to be the FSF/Cygnus aim -- e.g. the recent gdb snapshots, make-3.77 and perhaps also some other GNU tools can be configured only under the 'native' Win32 environment (without any fixes to the 'configure' script). All kind of "This feature cannot be checked under a cross-development environment" errors will result from trying to configure e.g. with : --build=i486-linux --host=i386-cygwin32 (or 'i386-mingw32/i386-go32') Of course all this is bullshit, e.g. the make-3.77 configure cannot look from the header prototype if the DJGPP setvbuf() uses the 'old' order of parameters: int setvbuf(FILE *_stream, int _mode, char *_buf, size_t _size); instead of the 'new' order (which DJGPP 2.02 uses) : int setvbuf(FILE *_stream, char *_buf, int _mode, size_t _size); or have a 'if [($host=go32) || ($host=cygwin32) || ($host=mingw32)]' condition for having data for some 'known systems' for which all tools may be built most easily in a cross-development environment... Instead the configure script sees the only way to be to test things with a short program, run in the 'build/host' system... Of course all these things don't disable one from fixing the 'configure' and giving it some known answers for DOS/go32, cygwin or mingw32 hosts, but anyhow having these kind of things there is a nuisance and not having them could be much better... Perhaps these "features a'la MS" (it doesn't matter which system you use when you only have a MS-approved opsys...) should be reported as bugs with fixes for them... Anyhow I still think that having only one piece of sources under *nix is much better regarding maintainability and after fixing the configure bugs, the whole build process is much easier... If the building of GNU tools for DOS and Win32 hosts was too easy under Linux or any other *nix system, who then would think to use DOS, Win95 or NT for this same purpose? So perhaps there is some sense behind these 'bugs' --- to get more and more people converted to the beautiful DOS/Windoze world. As a run-time systems DOS/Win32 are Ok, the toolmakers don't need to use them for anything else but testing the resulted executables. But if all the toolmakers also must use them, perhaps it could be just better to forget these hosts... (unless someone thinks to pay something for making tools for them -- e.g. it's allowed to waste one's work time for these jobs...). I don't know how the 'make.exe' was built for the DJGPP release, but being able to rebuild anything of these 'utilities' from sources for a DOS-hosted cross-toolset, if needed, and not needing to use DOS as the build environment, is what I prefer...
