tbutc-uses-not-thread-safe-status-20020725

"The multithreaded butc (src/tbutc/butc) includes bucoord/status.o, which is
compiled together with the other bucoord stuff without MT_CFLAGS and hence
without AFS_PTHREAD_ENV defined. Alas, it uses ObtainWriteLock and other
macros out of lock.h which *are* sensitive to AFS_PTHREAD_ENV. Consequently,
butc can hang trying to acquire the statusQueueLock when dumping volumes, in
particular if 'backup status' commands are issued frequently.

A proper fix would probably be to push some of those macros out of lock.h and
make them subroutines in lock.c.

A quick fix is ensuring status.c gets recompiled in tbutc/Makefile.in"
