I have just obtained GNU Make V3.57, having been using V3.27 up to now,
and there would appear to be a new bug in the handling of chained rules.

The following script illustrates the problem. The first make works OK, but
the second make, which should do nothing, screws up.

The makefile works fine with gmake 3.27.

If you have a fix for this, I would be very grateful if you would mail it to
me.

(Note: I am running make on a VAX, and the bug appears with both cc and gcc.)
