/* Note that these tests (specifically 1, 3a and 3b) fail when compiled with
 * clang and optimzing due to difference between clang and gcc, and more
 * interestingly, within clang itself: with optimization enabled, the entries
 * marked with "undef?" produce 0x80000000 instead of 0, but with optimization
 * disabled, the expected 0 is produced.
 * Inspecting the results, it seems that clang sets negative floats and doubles
 * to 0 when casting to unsigned long, but not consistently.
