Wed Jul  1 11:19:13 1998  Craig Burley  <burley@gnu.org>
	Fix 980701-1.f (which was producing "unaligned trap"
	on an Alpha running GNU/Linux, as predicted):
	* equiv.c (ffeequiv_layout_local_): Don't bother
	coping with pre-padding of entire area while building
	it; do that instead after the building is done, and
	do it by modifying only the modulo field.  This covers
	the case of alignment stringency being increased without
	lowering the starting offset, unlike the previous changes,
	and even more elegantly than those.
	* target.c (ffetarget_align): Make sure alignments
	are non-zero, just in case.
