PATCH: fix some minor problems in last checkin for BP case

[Greg McGary]

For the BP compiles, I had a couple problems with the last checkin, so
I committed this fix:

2000-07-26  Greg McGary  <greg@mcgary.org>

	* sysdeps/generic/bp-checks.h (BOUNDED_N): Make it work for void*.
	* sysdeps/generic/bp-semctl.h (check_semctl): Fix syntax error
	in union init.  Pass zero for ignored semnum arg to semctl.
	* sysdeps/unix/sysv/linux/shmat.c (shmat): Fix typo.
