*** empty log message *** cvs/libc-960906

Thu Sep  5 13:18:25 1996  Thomas Bushnell, n/BSG  <thomas@gnu.ai.mit.edu>

	* sysdeps/mach/hurd/i386/init-first.c (__libc_argc, __libc_argv):
	New variables.
	(init1): Initialize them.
	* hurd/hurdinit.c (_hurd_setproc): Now that happens to be
	available, pass __libc_argv in call to __proc_set_arg_locations.

	* gmon/gmon.c (write_hist): Call __profile_frequency instead of
	hertz. 
	(hertz): Delete function.
	* gmon/Makefile (routines): Add `prof-freq'.
	* sysdeps/generic/prof-freq.c: New file.
	* sysdeps/mach/hurd/prof-freq.c: New (stubby) file.
	* sysdeps/mach/hurd/profil.c (profile_tick): New variable.
	(update_waiter): Store frequency in profile_tick.
	(__profile_frequency): New function.

	* sysdeps/mach/hurd/sendto.c (sendto): Use prototype definition
	syntax.

	* Rules (generated): Restore reference to $(generated).

	* mach/Machrules (mig.uh, mig.__h): Don't include $(user-MIGFLAGS)
	here. 

 	* malloc/free.c (free): __lib_malloc_lock -> __libc_malloc_lock.
	
	* malloc/free.c: Provide extern decl of __libc_malloc_lock.
	* malloc/realloc.c: Likewise.
	* malloc/malloc-find.c: Likewise.
	* malloc/malloc-size.c: Likewise.
	* malloc/malloc-walk.c: Likewise.
	* malloc/memalign.c: Likewise.

  	* mach/Machrules (mig.uh, mig.__h): Include $(user-MIGFLAGS) and
