It's easy enough to test whether gcc will accept -msse and ifdef out the
intrinsics code

libspeex/SSE Intrinsics with GCC 3.3.x
...cc
being detected, the way -O3 is. These flags are pretty much never
portable, but it probably doesn't hurt to try.
The patch as written results in CFLAGS="-g -O2 -O3 -msee" if it
succeeds. You can avoid the duplicate optimization levels by saying
something like:
if test $ac_cv_prog_gcc = yes; then
dnl remove any existing gcc -On flag
oldcflags=`echo $old_cflags | sed -e 's/-O.//'`
OPT_CFLAGS="$OPT_CFLAGS -O3"
fi
OPT_CFLAGS="$OPT_CFLAGS -msse"
instead.
So perhaps not so simple, but writing expert systems in sh never...
