That should work if properly ifdeffed, yes. I didn't do it that way only 
because nobody else in Gnulib is doing it that way and there are 
problems with __attribute__((unused)) in older GCCs that I didn't want 
to do the research on. As I vaguely recall, __attribute__ ((used)) used 
to mean __attribute__ ((unused)), or was it vice versa?
