Mmm.. then how about putting following into snprintf() just before all
the includes:

#ifdef WIN32
#define __STDC__
#endif
#include ...
...

is there any docs for win32 on how va_start or VA_START is supposed to
be used? looks like related macros are not include here.

typedef unsigned char u_char

va_start/va_end macro probs..

as well.

then #ifdef WIN32 hack could help :-)

well, u_char is easy to solove.. either with 

#ifdef WIN32
#ifndef u_char
#define ....
#
#

or just replace u_char with unsigned char in the code. won't make much
difference.

can we have #define __STDC__ for sprintf() only then?
