Huh? I said exactly the opposite. To expose it as a __non-default__ replacement. I pointed at __mingw_printf, so to suggest programs would call it like __mingw_stat or something, or by defining __USE_MINGW_POSIX_STAT or something, just like one can define __USE_MINGW_ANSI_STDIO before including stdio.h. I'll understand if you wouldn't want to support that as an option, but I did _not_ suggest making it the default. > This would change documented and exprected behavior of > msvcrt's implementation.

Makefiles were an obvious example -- if the preprocessor needs needs to find the right include files, so must Make need this to pick the right dependencies, isn't it? This sort of potencially-needing-to-be-fixed-in-many-places issue is what makes me believe a much better solution would be to just not rely on this semantics in the first place. > I think that libiberty is exactly present to unify functionality (and > API) for different operation systems.

I'd be nice if gcc used that instead for the host abstraction parts (gdb does), but nobody's working on that afaik... > I agree that there are other venture, which might be affected by same > problem.
