-dnl -ffast-math removed January 12, 2013.  Don't re-add it, nor any of its sub-options(ESPECIALLY not -funsafe-math-optimizations),
-dnl it messes up certain code(NES resampler, for example) under certain conditions and alignments of the great celestial squid.
-dnl
-dnl In fact, let's explicitly disable it here with -fno-fast-math.
-dnl
-dnl -fomit-frame-pointer is required for some x86 inline assembly to compile.
-dnl
-dnl November 28, 2014: Use -fwrapv unconditionally instead of -fno-strict-overflow, -fno-strict-overflow is buggy
-dnl and does not work as documented/implied.
