Re: malloc.m4 should treat mingw like posix

Really?  They use very different implementations; my understanding (although it 
may be limited, since I don't follow mingw development) is that mingw defers to 
the Microsoft malloc, and I'm not convinced that errno is handled properly in 
mingw, nor that malloc(0) allocates memory instead of acting as a no-op.  
Cygwin, on the other hand, uses its own malloc which does indeed meet the 
gnulib requirements.

Do you have a pointer into the MSDN pages or the mingw source code that can 
back up your claim, before we consider applying this patch?

If mingw truly is POSIX compliant, does that leave any _WIN32 implementations 
which aren't?
