WineLib with MSVCRT

What is the proper way to use the MSVCRT in WineLib?
I tried adding a -I/usr/local/include/wine/msvcrt to the
list of includes and -nostdinc to CXXEXTRA, but then gcc
can't find stdarg.h, which is included in windows.h via
winbase.h.

If I use -nostdinc++, gcc is able to find stdarg.h, but it runs
into problems with other files, such iostream.h.

Finally, if I don't use either -nostdinc or -nostdinc++,
gcc complains about types being redefined, such as wint_t
(as an unsigned short int in /usr/include/_G_config.h but
WCHAR in /usr/local/include/wine/msvcrt/wctype.h).

It seems like using -nostdinc would be the right way, but
does that mean that Wine needs to include its own copy
of stdarg.h and related files?

Check out how Wine programs (e.g. regedit) use MSVCRT.

I just stumbled into the same problem.

I worked around this by adding a few lines to the wine header
files - see patch below - and at least my code compiles now. I can't
tell if it runs, but it may be worth a try.

It may also depend on the gcc/libc versions installed, though :/
Perhaps someone with more insight into wide characters/libc/gcc
can comment.

--nostdinc obviously carries tons of problems, I've given up on it.
