Unfortunately, there was a bug in these tests, with the consequence
that the value wasn't checked (so, these tests could only detect
assertion failures or freeze). I've just fixed it and another bug
in reciprocal trig/hyperbolic functions which wasn't detected because
of that. If GCC calls these functions with all the flags cleared, it
isn't affected by this bug.

Moreover there is now an mpfrlint script (available via Subversion)
that can be used to detect bad constructs; it should have detected
the above bug, but was incomplete. Again, fixed.
