Please check it in.
I just built a gcc 4.3.4 Linux->Cygwin cross compiler using the sources from the Cygwin 1.7 distro. I used the following build flags: --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 When I try to build Cygwin I get: cc1plus: error: command line option '-muse-libstdc-wrappers' is not supported by this configuration What am I doing wrong?
