Hello,
I just wanted to report that the change to shortest-stem pattern
matching in make-3.82 breaks the GNU-make based build-system, GAR.
I'm using GAR to build all the released GNU packages on the GCC
compile farm (http://chapters.gnu.org/~bjg/gsrc/summary/).
The GAR makefiles were written using the order-based matching and
pretty much rely on it (example below). I'm not sure they can be
easily modified to work with make-3.82 so some way to get the old
behavior for compatibility would be appreciated.

Example: there's an http//% target at the top of the GAR Makefile so
make http//ftp.gnu.org/gnu/patch/patch-2.6.1.tar.gz
would always match it and download patch-2.6.1.tar.gz under make-3.81.
Under make-3.82 this fails whenever the url happens to end in a string
that matches another pattern rule in the Makefile (e.g. patch-%).
There are many other pattern rules (approx 100) and the URLs are
arbitrary so it's a real problem in practice.
# download an http URL (colons omitted)
http//%:
wget $(WGET_OPTS) -O $(DOWNLOADDIR)/$(notdir $*).partial http://$*
mv $(DOWNLOADDIR)/$(notdir $*).partial $(DOWNLOADDIR)/$(notdir $*)
