* lib/pthread.in.h: If REPLACE_PTHREAD_RWLOCK_INIT is 1 but REPLACE_PTHREAD_RWLOCK_DESTROY is 0, override PTHREAD_RWLOCK_INITIALIZER. * lib/pthread-rwlock.c (pthread_rwlockattr_init) [PTHREAD_RWLOCK_BAD_WAITQUEUE]: New function. (pthread_rwlock_init) [PTHREAD_RWLOCK_BAD_WAITQUEUE]: New function. * m4/pthread-rwlock.m4 (gl_PTHREAD_RWLOCK): Check for reasonable pthread_rwlock wait queue handling. Set REPLACE_PTHREAD_RWLOCK_INIT and REPLACE_PTHREAD_RWLOCKATTR_INIT and define PTHREAD_RWLOCK_BAD_WAITQUEUE if not. * modules/pthread-rwlock (configure.ac): Update GL_COND_OBJ_PTHREAD_RWLOCK condition. * doc/posix-functions/pthread_rwlock_rdlock.texi: Mark the glibc problem as fixed. * doc/posix-functions/pthread_rwlock_tryrdlock.texi: Likewise. * doc/posix-functions/pthread_rwlock_timedrdlock.texi: Likewise.
