Checked on x86_64-linux-gnu and i686-linux-gnu. * nptl/tst-sem5.c: Remove unused headers. Add <support/check.h>. (do_test) Use libsupport test macros rather than hand-coded conditionals and error messages. Ensure that sem_init returns zero rather than not -1. Use <support/test-driver.c> rather than test-skeleton.c. * nptl/tst-sem13.c: Add <support/check.h>. (do_test) Use libsupport test macros rather than hand-coded conditionals and error messages. Use <support/test-driver.c> rather than test-skeleton.c.
