# The follow CFLAGS are a work around for GCC Bugzilla Bug 29253
# "expand_abs wrong default code for floating point"
# As this is not a regression, a fix is not likely to go into
# gcc-4.1.1 and may be too late for gcc-4.2. So we need these flags
# until the fix in a gcc release and glibc drops support for earlier
# versions of gcc.
#
# This bug can cause wrong signs of zero results from fabsl, and
# spurious "invalid" exceptions from comparisons with NaN in the
# default code sequence generated. The fpclassify expansion used by
# __builtin_fpclassify, which is used in the absence of
# -fsignaling-nans, uses __builtin_fabsl, and is not affected by
# -fno-builtin-fabsl, so requiring -fsignaling-nans for some affected
# source files.
