Q: Why do some 32-bit MinGW-w64 applications fail with '...
_vswprintf
could not be located in the dynamic link library msvcrt.dll' on
Windows
XP SP1?
A: For C++, MinGW-w64 implements 'vswprintf (wchar_t *__stream,
const
wchar_t *__format, __builtin_va_list __local_argv)' as a call to
'_vswprintf'. Older versions of msvcrt.dll, like the version in
XP SP1,
do not include '_vswprintf'. A workaround for this is to compile
any
C++ libraries and applications that use 'vswprintf' (with the
preceding
signature) with -D__USE_MINGW_ANSI_STDIO. For example, to build the
wxWidgets library for applications to be deployed on XP SP1, build
wxWidgets with the following command line:
> mingw32-make -f makefile.gcc
CPPFLAGS="-D__USE_MINGW_ANSI_STDIO"
Done as
https://sourceforge.net/apps/trac/mingw-w64/wiki/_vswprintf%20missing.
Thanks.
I've also added a caveat section on the side effects of using
__USE_MINGW_ANSI_STDIO.
Well, IMO we should fix bugs instead of documenting them... I may look
at this, but I'm not sure when I will find time for that.

Well, in general I agree. We might should do same hack (for older
msvcrt versions) as we do for vscanf (as example).
Cheers,
Kai
Can we do _vswprintf == vswprintf again?
And XP SP3 msvcrt.dll doesn't contain _vswprint, too.
We must fix it!
I'm sorry, I forgot about this before I found the time to fix it. Can
you prepare a patch?
Thanks,
Jacek
Same with vsnprintf
