[bug #9062] Need access to pathname of Makefile

[Nikolay Molchanov]

Follow-up Comment #6, bug #9062 (project make):

I tried to use ${CURDIR} and ${MAKEFILE_LIST} with a GNU make 
on Solaris, but these variables are empty. In what version of 
GNU make they appear? I think they work in 1.80, correct?
Here is what I tried:

% uname -a
SunOS volga2 5.9 Generic_112233-07 sun4u sparc SUNW,Ultra-60
% gmake -version
GNU Make version 3.74-96q4, by Richard Stallman and Roland McGrath.

% cat Makefile
d=${CURDIR}
m=${MAKEFILE_LIST}

all:
        echo "Directory = $d"
        echo "CURDIR=${CURDIR}"
        echo "Makefile = $m"
        echo "MAKEFILE_LIST=${MAKEFILE_LIST}"

% gmake
echo "Directory = "
Directory =
echo "CURDIR="
CURDIR=
echo "Makefile = "
Makefile =
echo "MAKEFILE_LIST="
MAKEFILE_LIST=


There is a standard env. variable ${PWD}, which contains the path
to the current directory. It is supported by Solaris make, GNU 
make, and some other make utilities.
