1998-07-24 Martin Baulig <martin@home-of-linux.org> * sysdeps/{kernel, linux}/*.c: Replaced `glibtop_init_r' with `glibtop_init_s'. * sysdeps/sun4/open.c (glibtop_init_p): Removed `program_name' parameter. * sysdeps/osf1/glibtop_suid.h: New file. * sysdeps/osf1/glibtop_server.h: Now correctly using `(1 << GLIBTOP_SYSDEPS_*)' instead of `GLIBTOP_SYSDEPS_*'. * sysdeps/osf1/open_suid.c (glibtop_init_p): New function. * sysdeps/osf1/proc*.c: Done some more work here.
