Yep. Another thing I just thought of is that it would be good (if you have
time) to write your test for each of the types float, double and long
double - all should work in gcc.

The only caveat is, of course, not to rely on the format :-). e.g. on some
targets double's are 32-bits (yes, really. Some HW manufacturers should be
shot for specifying ABIs like that).
