Yes it needs -ffast-math. Right now, you need -ffast-math to convert:
a = (b >= c) ? b : c;
into a max, but you don't for:
a = (b > c) ? b : c;
p9-minmax-1.c tests whether both cases are handled with -ffast-math, while
p9-minmax-2.c tests whether just the second case is handled without
-ffast-math.
