Hi, Just to let people know I have succeeded in building gcc-4.7.0 with --enable-build-with-cxx (All stages built as C++) on latest Cygwin with GCC 4.5.3 and on MinGW32 with a rebuilt GCC 4.6.2 as the GCC 4.6.2 that came with MinGW was missing stdarg.h and stddef.h and possibly other headers.
Many thanks, Aaron
