Enable test_stack for pthreads-w32

* tests/test_stack.c: Do not skip this test if AO_USE_WIN32_PTHREADS.
* tests/test_stack.c (main): Report (to stdout) if the test skipped;
always include stdio.h.
* tests/test_stack.c (LIMIT): Allow to specify alternate value from
command line; use smaller value (by 50 times) if AO_USE_PTHREAD_DEFS.
