Update.
2003-01-02  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/pthread/bits/pthreadtypes.h (pthread_cond_t): Add padding.
	* condvar.c: Add symbol versioning.  The compatibility versions
	are the same as the change in the interface does not effect this
	implementation.
	* Versions [libpthread]: Add definitions for new pthread_cond_*
	interfaces for version GLIBC_2.3.2.
