See PR 19405 > and <http://gcc.gnu.org/ml/gcc-patches/2005-01/msg00374.html>. But why do both that exact testcase and the libstdc++ one fail with this LDFL_EPSILON value on IRIX, and disagree with both the one from the system headers, which is identical to the one found in the gcc.target/powerpc/rs6000-ldouble-2.c test?
