I tried to use your trick. In a header, I use that:

#if defined(__MSDOS__) || defined(__EMX__) || \
    (defined(_WIN32) && !defined(_UWIN) && !defined(__CYGWIN__) && 
!defined(__CEGCC__))
# if defined(_MSC_VER) || defined(__MINGW32__)
#  define open(path,flag,mode) _open((path),(flag),(mode))
#  define close(fd) _close(fd)
#  define read(fd,buffer,count) _read((fd),(buffer),(count))
#  define write(fd,buffer,count) _write((fd),(buffer),(count))
#  define unlink(filename) _unlink((filename))
#  define mkdir(p,m) _mkdir(p)
# endif
#endif

but stdio.h is also included. Hence, I have a lot of conflicts (especially 
in io.h, but also in stdio.h, like:

D:/msys/1.0/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/io.h:171:55: 
macro "mkdir" requires 2 arguments, but only 1 given

or

D:/msys/1.0/mingw/bin/../lib/gcc/mingw32/3.4.5/../../../../include/stdio.h:187: 
error: syntax error before '(' token


any idea about what I should do ? defining NO_OLDNAMES and _NO_OLDNAMES 
before stdio.h ?

thank you

Vincent Torri
