Hm. I'm no longer able to reproduce this result, so I may be 
misremembering that detail. At present, with my definition removed, I 
get build failures for test-pthread and test-pthread-rwlock (using 
"make -k").

That gives me the same compile error as a full build:

Whatever magic exists to work around a missing PTHREAD_RWLOCK_INITIALIZER,
I'm not seeing it...
