With RedHat 6.0, it seems that __USE_UNIX98 must be turned on in order
for the pthread_rwlock_t to be defined. I think more autoconf is
needed here. (If nobody else gets to it, I'll handle but no timeframe
promised :) I'm behind with too many promises already.)

This is what fails to compile with RH 6.0. We found
pthread_rwlock_init() but didn't test for pthread_rwlock_t
without/with __USE_UNIX98.
