As the maintainer of devel/mingw32-gcc, it currently needs staging, but the port
refuses to compile at the moment. The first problem I was getting was it saying
that it couldn't find stdio.h at all.
After a bit of searching on Google, I found the --with-sysroot configure option.
I had to patch gcc/config.gcc to use /mingw32/include instead of /mingw/include
(since devel/mingw32-bin-msvcrt installs to ${PREFIX}/mingw32/include).
I have attempted to build the port in poudriere.
If I set --with-sysroot to ${PREFIX}, I get the following:
The directory that should contain system headers does not exist:
/prefix/mingw32-gcc-4.8.1_1/mingw32/include
gmake[2]: *** [stmp-fixinc] Error 1

gmake[1]: *** [all-gcc] Error 2
gmake[1]: Leaving directory `/wrkdirs/usr/ports/devel/mingw32-gcc/work/build'
gmake: *** [all] Error 2
If I set --with-sysroot to ${LOCALBASE}, I get the following instead:

I'm at a complete loss as to how to fix this. I am hoping that someone more
versed in cross-compiling gcc can help me solve this, so I can get the port
updated and staged before the end of the month.
Thanks,
