*printf-posix: Avoid test failures. Make tests work on MacOS X, Cygwin. * tests/test-fprintf-posix3.c: Include "resource-ext.h". (main): Perform test also when getrlimit and setrlimit don't exist or when setrlimit of RLIMIT_DATA fails (like on Cygwin). Instead of limiting the address space size using setrlimit, compare the address space size before and after the the test. * tests/test-dprintf-posix2.c: Likewise. * tests/test-fprintf-posix3.sh: Update skip messages. * tests/test-dprintf-posix2.sh: Likewise. * modules/fprintf-posix-tests (Depends-on): Add get-rusage-as. * modules/dprintf-posix-tests (Depends-on): Likewise. Reported by Bruce Korb <bkorb@gnu.org> and Gary V. Vaughan <gary@gnu.org>.
