Something must be missing, because if I remove my conditional definition
of PTHREAD_RWLOCK_INITIALIZER from pthread.in.h, test-pthread-rwlock is
no longer in the set of tests built by default. If I then attempt to
build it manually, I get the following error:

make: *** [test-pthread-rwlock.o] Error 12

(Note that all my Gnulib work is done in a testdir tree created using
gnulib-tool; my presumption is that this should set up everything
correctly from the get-go.)
