linux->mingw cross and latest gcc snapshot

[Florian Wunderlich <fwunderlich at devbrain dot de>]

I tried to build a cross compiler from Linux to Mingw for the latest gcc
snapshots (20010205 and 20010305), and the compilation stops because of
some undeclared symbols in ctype_base.h. The same snapshot compiles as a
native compiler on Linux, and the symbols really are undeclared as far
as I can tell, so this is not a bug in the compiler.

Configuration: --prefix=/opt/gcc-mingw32 --target=i386-mingw32
--with-gnu-as --with-gnu-ld 	--enable-shared i586-linux

i386-mingw32/libstdc++-v3/include/bits/ctype_base.h in the build
directory is linked to libstdc++-v3/config/os/newlib/bits/ctype_base.h
in the source directory.

Here are the error messages:
