It would be very much appreciated if you could provide me the missing settings
for my configure command line arguments which look for the moment like this:

--prefix=/FaF --infodir=/FaF/share/info --mandir=/FaF/share/man
--libdir=/FaF/lib64 --libexecdir=/FaF/lib64 --enable-languages=c,c++ 
--enable-checking=release --with-gmp=/FaF/ --with-mpfr=/FaF --with-gmc=/FaF
--with-gxx-include-dir=/FaF/include/c++/7.3 --enable-ssp --disable-libssp
--disable-plugin --with-bugurl=http://bugs.opensuse.org/
--with-pkgversion='SUSE Linux' --disable-libgcj --disable-libmudflap
--with-slibdir=/lib64 --with-system-zlib --enable-__cxa_atexit
--enable-libstdcxx-allocator=new --disable-libstdcxx-pch
--enable-version-specific-runtime-libs --enable-linker-build-id
