--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-12-08 19:52:01 UTC --- For __float128 detection, there is now a patch at: http://gcc.gnu.org/ml/fortran/2010-12/msg00045.html However, one still might change the configure check for symbol versioning. As there have been already several commits, which also affect cross building: Can someone confirm that building GCC on a bare iron machine still fails due to the libquadmath configure script?
