*** 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
