I'm not entirely sure this is a bug, but the expansion of macros in
the VPATH macro does not appear to behave reasonably. Consider the
following makefile:
OD = /mit/bjaspan
VPATH = ${OD}
foo: bar.o
-echo ${VPATH}
(The file bar.o exists in the CURRENT directory, which also happens to be
${OD}.) make produces the error "Directory ${OD}: Make: Cannot open. Stop."
It appears as if VPATH is just taking the literal string, and not
expanding.
However, if foo's dependency on bar.o is removed, the echo command
does in fact echo "/mit/bjaspan" on the screen.
