It's tough to read much into your test, since gcc will likely simplify
everything away at compile time.  It would be better to test calls to
the library routines in separately compiled C files, as they are in
libmlton.  You could have your C code call Word{8,16,32,64}_{quot,rem}
and link with libmlton.a.  Running through all pairs of args from -100
to 100 should be a pretty good test.
