	cygwin         : ChangeLog thread.cc thread.h 

Log message:
	* thread.cc (pthread_rwlock::lookup_reader): Remove parameter: always assume
	that we're looking for the current thread.
	(pthread_rwlock::tryrdlock): Eliminate self variable.  Accommodate change in
	lookup_reader().
	(pthread_rwlock::unlock): Ditto.
	(pthread_rwlock::rdlock): Ditto.  Move add_reader call after writer tests to
	more closely mimic old behavior.

	* thread.h ((pthread_rwlock::lookup_reader): Eliminate argument.
