After updating gnulib master, the "make" step now ends with the error:

gcc -std=gnu99 -DHAVE_CONFIG_H -DEXEEXT=\"\" -I. -I..  -DGNULIB_STRICT_CHECKING=1 -DIN_GNULIB_TESTS=1 -I. -I. -I.. -I./.. -I../gllib -I./../gllib   -Wno-error -g -O2 -MT test-pthread.o -MD -MP -MF $depbase.Tpo -c -o test-pthread.o test-pthread.c &&\
mv -f $depbase.Tpo $depbase.Po
test-pthread.c:35: error: ‘PTHREAD_RWLOCK_INITIALIZER’ undeclared here (not in a function)
make[4]: *** [test-pthread.o] Error 1

Same or similar results with GCC4 and GCC7.
