Ulrich Drepper 51d46f733a Update.
2002-07-25  Ulrich Drepper  <drepper@redhat.com>

	* sysdeps/wordsize-32/divdi3.c: Define __divdi3_internal.
	* sysdeps/wordsize-32/lldiv.c: Make gcc use __divdi3_internal instead
	of __divdi3.

	* sysdeps/unix/sysv/linux/adjtime.c: Use __adjtimex_internal.
	* sysdeps/unix/sysv/linux/ntp_gettime.c: Likewise.
	* sysdeps/unix/sysv/linux/syscalls.list: Add __adjtimex_internal
	alias for adjtimex syscall.

	* elf/dl-minimal.c: Define __assert_fail_internal.
	* assert/assert.c: Likewise.
	* include/assert.h: Define __assert_file macro if !SHARED and not
	NOT_IN_libc.

	* iconv/Makefile: Define NOT_IN_libc for objects in standalone
	programs.
	* locale/Makefile: Likewise.
	* nscd/Makefile: Likewise.
	* catgets/Makefile: Likewise.

	succesful seek call.  Simplify error checking.
