I'm trying to use GNU Make 3.54 on a Sun-3/160 running SunOS 4.0.3.  I've
found unexpected behavior which I believe to be a bug.  When a file is located
using VPATH, its modification time is not used correctly.

My 1-line Makefile:
    VPATH = obj

Repeat by:
    mkdir sub obj
    echo >obj/test.o
    echo >test.c
    # make sure that test.c is newer than obj/test.o
    make -n test.o

Make says
    `obj/test.o' is up to date.
even though test.c is newer than test.o.  I expected Make to notice that the
object file is older than the source file and issue a cc command.
