Update.

	* sysdeps/unix/i386/i686/tempname.c: New file.

	* sysdeps/posix/tempname.c (__gen_tempname): If RANDOM_BITS is
	defined use this macro to get some bits of randomness instead of
	the usual gettimeofday or time calls.

2001-03-16  Paul Eggert  <eggert@twinsun.com>

	* sysdeps/posix/tempname.c (uint64_t): Define to uintmax_t if
	not defined, and if UINT64_MAX is not defined.
