I built a linux->mingw cross compiler for the last egcs releases and for
gcc-2.95 and 2.95.2, with the same setup. But this was of course
libstdc++-v2, but we need v3 now. So this is the first time with a
post-2.95.2 version.

Sorry, I don't have a native toolchain for mingw32.

It works when I link ctype_base.h, ctype_inline.h, ctype_noninline.h,
os_defines.h from generic. Where do these symbols come from for cygwin?
And shouldn't they also be defined for mingw?

Thanks for your help.
