+I read some web pages and then did an experiment; GNU make (v 3.77+)
+has builtin variable $(CURDIR). $(PWD) gets value from environment:
+
+doing the following:
+
+$ cat > foo.mk <<EOF
+all:
+        pwd=`pwd`; echo $pwd
+        echo $(CURDIR)
+        echo $(PWD)
+EOF
+$ PWD= make -f foo.mk
+pwd=`pwd`; echo $pwd
+/home/too
+echo /home/too
+/home/too
+echo 
+
+$ cd ..
+$ make -C too -f foo.mk
+make: Entering directory `/home/too'
+pwd=`pwd`; echo $pwd
+/home/too
+echo /home/too
+/home/too
+echo /home
+/home
+make: Leaving directory `/home/too'
+
+
+So, most portable option would be using pwd=`pwd`; echo $pwd
+construct in the makefile. Next option would be using $(CURDIR)
+and it works with -C (and with original bourne shell which does
+not manage $PWD). That is GNU make (v 3.77+) spesific but the makefiles
+use GNU make constructs elsewhere too.
