Version 3.48 of Make doesn't handle double colon rules correctly in
some cases.  This simple Makefile produces the correct results with
Make 3.48:

   test::	/bin/true
	   echo "hello 1"

   clean:: 
	   rm myprog

   test::  /bin/echo
	   echo "hello 2"

When I'm using Make version 3.48 to install X11, however, it seems to
only notice the first double colon rule.  In the following Makefile,
incorrect results occur for the targets "relink", "install" and
"clean".

I've tried Make 3.48 on a Sun 3 running SunOS 4.0.1, a Sun 4 running
SunOS 4.0.1, and a Sequent Symmetry S81 running Dynix 3.0.12, each time
comparing Make version 3.48 to the vendor's /bin/make.

By the way, the Makefiles used in generating and installing X11 are full
of double colon rules.

Using the "-p" option when executing Make 3.48 shows that only one of 
each of the double colon rules appears in the data base.
