--- Comment #4 from Tobias Burnus <burnus at gcc dot gnu.org> 2010-11-26 13:45:31 UTC --- (In reply to comment #3) > Same problem on SPARC/Solaris 8 and 9 (but not 10). SPARC has quad precision > floating point support but Solaris 8 and 9 aren't C99; only Solaris 10 is. There is a simple solution: Simply not using a C99 long double math function ... That won't test complex libquadmath functions anymore, but one can defer that to a libquadmath testsuite, if needed.
