This is especially important for command line given variables, and this prevents NSS from building successfully with pymake. The following Makefile exposes the problem:

----8<------
FOO=TEST-FAIL

foo:
        @$(MAKE) --no-print-directory -f test.mk bar FOO=TEST-PASS

bar:
        @$(MAKE) --no-print-directory -f test.mk baz

baz:
        @echo $(shell $(MAKE) --no-print-directory -f test.mk echo-foo)

echo-foo:
        @echo $(FOO)
----8<------

With GNU make, the output is TEST-PASS, with pymake, it's TEST-FAIL.

Note that if the foo rule calls baz directly, GNU make prints TEST-FAIL. This has to do with the MAKEFLAGS variable making it in the subshell in one case and not the other (you got to love GNU make).

Looks like bug 787600 fixed this.
