Bugzilla Bug 119592

On both an x86 with gcc 3.3 and a hppa system with 3.3,
dev-cpp/libherdstat-0.2.0 doesn't build. The error messages look like this:

Okay, I'm getting the same error. It looks like the problem is caused by the
LIBHERDSTAT_UNUSED macro, which is part of the signature in the *.cc but not in
the *.hh. The compiler seems to be punishing us for this.

Fixed.
