Greetings...

This is a really strange bug.  The following Makefile causes GNU Make 3.54
to core dump but not GNU Make 3.48.  Changing the Makefile by for instance
removing the line 'dir: dir.o' or removing one of the elements of AMSMODULES
seems to make the bug go away.

yunexus$ ls
Makefile	Makefile~	core
yunexus$ cat Makefile

AMSMODULES= util.o bm.o io.o crc32.o queue.o groups.o databases.o field.o authorize.o userlog.o menu.o lastlog.o amsfunc.o quotas.o

dir: dir.o

libams.a: $(foreach filename, $(AMSMODULES), libams.a($(filename)))
	ranlib $@
