	to elf_machine_matches_host.
	* sysdeps/alpha/dl-machine.h (elf_machine_matches_host): Parameter
	is now pointer to ELF header.

2000-10-20  Jakub Jelinek  <jakub@redhat.com>

	* include/limits.h: Include bits/wordsize.h, use #if __WORDSIZE == 64
	check instead of #ifdef __alpha__.
	* include/bits/xopen_lim.h (WORD_BIT, LONG_BIT): Don't count on
	INT_MAX, __INT_MAX__, LONG_MAX or __LONG_MAX__ being defined when
	this is included.

	* posix/wordexp-tst.sh (testout): Place output file in build
	directory.  Patch by Joseph S. Myers <jsm28@cam.ac.uk>.
