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 \
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?
