	* sysdeps/unix/sysv/linux/sysconf.c (__sysconf)
	<case _SC_MONOTONIC_CLOCK>: Return _POSIX_VERSION instead of 1.

2004-05-07  Jeroen Dekkers  <jeroen@dekkers.cx>

	* sysdeps/mach/hurd/i386/Makefile (CFLAGS-init-first.c): Add
	-momit-leaf-frame-pointer.

	* inet/test-ifaddrs.c (addr_string): Surround AF_PACKET case with
	#ifdef AF_PACKET.

	* sysdeps/mach/hurd/getcwd.c
	(_hurd_canonicalize_directory_name_intern): Only realloc when
	size is <= 0.

	* sysdeps/mach/hurd/mmap.c (__mmap): Fail when addr or offset
	isn't page aligned.

	* sysdeps/mach/hurd/spawni.c (EXPAND_DTABLE): Set dtablesize to
	new size.

	* sysdeps/mach/hurd/Versions (GLIBC_PRIVATE): Add __libc_read,
