Update.

	* sysdeps/unix/sysv/linux/kernel-features.h: Define
	__ASSUME_UTIMES for x86 and kernels > 2.5.75.

	* sysdeps/unix/sysv/linux/futimes.c (__futimes): Handle case with
	second parameter == NULL.
	* sysdeps/unix/sysv/linux/utimes.c: New file.

2003-07-12  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/futimes.c: Include kernel-features.h.
	* sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_UTIMES): Fix
	a typo.
