machdep/sunos-4.1.3/__stdlib.h : typedef pthread_size_t size_t
        Bug reported by grib@arlut.utexas.edu (William Gribble)

pthreads/fd.c : Fix bug with fd_free(), dup(), dup2(), and close(),
        where a fd gets lost after a dup() then close(). Added 
		fd_basic_basic_unlock() to unlock a fd_table[] by pointer and
        not an array index. 
		Bug reported by snl@PANEER.NDIM.EDRC.CMU.EDU (Sean Levy)

pthreads/fd_kern.c : The fd_table[fd]->flags of the fd that accept()
        returns should be the same as those of the fd passed to accept().
		Bug reported by doneill@unixg.ubc.ca (David O'Neill)

pthreads/select.c : Move pthread_sched_prevent() inside the statement.
		if (machdep_sys_select(...) == OK) 

stdio/fclose.c : Don't call funlockfile(fp) after fp->_file has been closed. 
		There is no need. Part of same bug as fd_free() problem above.

tests/test_pthread_mutex.c : Fix an error message.

tests/test_stdio_1.c : Rewritten.
