AC_DEFUN([BAR], [AC_SUBST([GREPBAR])])

I want to make sure that if configure.in is changed to require
bar.m4 instead of foo.m4, and if foo.m4 disappears, Make
successfully rebuilds everything to the point that Makefile
contains a definition for GREPBAR.

Yes.

And s/FOO/BAR/ here !

I think it's user-damage mostly, but I'll have to wait for the
next occurrence...
