Note, the proc_ptr_comp_45.f90 testcase fails on i686-linux (unless
-mfpmath=sse -msse2
or -ffloat-store) even at -O0, cos (1.570796327) is folded into constant and
the runtime
function doesn't return exactly the same result, because of extended
precision.
So, either you should allow a few ulps epsilon, or use some other function
where you get reasonably exact result.
