The libtool in the GCC tree seems to need --enable-win32-dll to build DLLs for Windows runtimes, which it would use only if the library defines AC_PROVIDE_AC_LIBTOOL_WIN32_DLL - I defined: AC_DEFUN([AC_PROVIDE_AC_LIBTOOL_WIN32_DLL],[]) in libstdc++-v3's configure.ac and regenerated configure. libtool also wants ld_shlibs to be set to "yes" and this I achieved by putting "ld_shlibs=yes" under the case label for "mingw*" in ltcf-cxx.sh. With these kludges, GCC tries to build libstdc++ as a DLL, but fails with undefined references to a whole bunch of stuff (crossed-native build on Linux). I'll investigate this issue later.
