Tobias Burnus <burnus at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |FIXED --- Comment #5 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-12-10 12:41:14 UTC --- Close as FIXED. You now have: --disable-libquadmath to disable the configure and build of libquadmath/ --disable-libquadmath-support to disable the __float128-based REAL(16) support in gfortran and the dependence of libgfortran on libquadmath. The two options are can be used independently from each other; if you use only the first one (and build Fortran), you have to make a (the system's) libquadmath library available to configure.
