From a2fe9c76a9d7645c63288eda807e01a6b1901d29 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Sat, 20 May 1995 00:13:43 +0000 Subject: Fri May 19 17:16:46 1995 Roland McGrath * sysdeps/mach/hurd/i386/init-first.c: In cthreads case, handle args on stack from kernel. * posix/Makefile, sysdeps/alpha/Makefile, * sysdeps/mach/hurd/Makefile, sysdeps/sparc/Makefile, Makefile, * Makerules, Make-dist: Fix "cvs commit" cmds in rules to not fail in the absence of CVS dirs. * hurd/hurdstartup.c: Don't call __mach_init. Grok args from the kernel on the stack properly. * set-init.c: Never call _init/_fini; just run __libc_subinit. * Makerules (LDFLAGS-c.so): Add -nostartfiles. * mach/Machrules (LDFLAGS-$(interface.so)): Likewise. * configure.in: Move defaulting of --with-elf and --with-gnu-* based on host os outside the AC_CACHE_VAL for the sysdirs calculation. * Makeconfig (localedir, nlsdir): New variables. * values.h: New file. * Makefile (headers): Add values.h. * locale/Makefile (distribute): Add error.h. * locale/localedef.c: Include "error.h". (main): Use error_message_count instead of warning_cntr. --- hurd/hurdstartup.c | 36 ++++++++++++++++-------------------- 1 file changed, 16 insertions(+), 20 deletions(-) (limited to 'hurd/hurdstartup.c') diff --git a/hurd/hurdstartup.c b/hurd/hurdstartup.c index 0347234397..416cddb62b 100644 --- a/hurd/hurdstartup.c +++ b/hurd/hurdstartup.c @@ -78,9 +78,6 @@ _hurd_startup (void **argptr, void (*main) (int *data)) int argc, envc; int *argcptr; - /* Basic Mach initialization, must be done before RPCs can be done. */ - __mach_init (); - if (err = __task_get_special_port (__mach_task_self (), TASK_BOOTSTRAP_PORT, &in_bootstrap)) LOSE; @@ -104,21 +101,19 @@ _hurd_startup (void **argptr, void (*main) (int *data)) if (err || in_bootstrap == MACH_PORT_NULL) { -#if 0 /* Either we have no bootstrap port, or the RPC to the exec server failed.
