[Mingw-users] contributing vscanf implementation

[<AWL...@ao...>]

hi,

a few days ago i wrote a small set of vscanf functions to
compliment the rest of the scanf functions provided
by mingw.  they use evil inline asm hacks to convert
the va_list functions back to normal varargs functions
(thus maintaining complete compatibility with the rest of the
c library)

provided are all of the missing *vscanf functions for both char and wchar_t:
vfscanf
vfwscanf
vscanf
vsscanf
vswscanf
vwsanf

i wrote this as part of my hax0ring to get libstdc++-v3 to
work the way i'd like it to on mingw.  if anyone else is
also working on this, let me know..

code is availible at
http://members.aol.com/awlaframboise/vscanf.tgz
it is public domain.

id love for this code to be integrated with the mingw
runtime.  if the maintainers think it should be integrated,
they are welcome to do so.  or, if they are busy, and im
sure they are, maybe someone would tell me how i would best
add this myself..

this will make the libstdc++-v3 configure script pass
the test for c99 wchar functions (combined with linking
against -lmsvcp).. but will not satisfy the silly xpg2
wchar requirement.

thanks,
