Hmm, I'm not quite sure. I recall that I asked Dave in PM about a
problem with libstdc++v3, but AFAICS the final set of configure options
fixed that. I *think* it was the --with-newlib option. Here's the
complete set:
--prefix=/opt/redhat/cross-cygwin \
--target=i686-pc-cygwin \
--disable-bootstrap --enable-version-specific-runtime-libs \
--enable-static --enable-shared --enable-shared-libgcc \
--disable-__cxa_atexit --with-gnu-ld --with-gnu-as --with-dwarf2 \
--disable-sjlj-exceptions --enable-languages=c,c++ --disable-symvers \
--enable-threads=posix --with-arch=i686 --with-tune=generic \
--with-newlib
