The point is that ${SCRIPT} is substituted in the Makefile by (1) a macro specified on the command line (2) a macro specified in the Makefile (3) an environment variable in that order, or with (2) and (3) reversed if Make is invoked with the "-e" switch. When the Makefile's command lines are passed to the shell, the substitution has already taken place, so it should also work with the Windows command prompt. However, one needs a Make program, i.e. a parameterization of this kind probably doesn't work with non-Makefile generators. Even with Makefiles, there are subtle pitfalls: If a line "SCRIPT = ..." happens to appear somewhere in the Makefiles, invoking Make as "make SCRIPT=..." will overwrite it, most certainly resulting in surprising and undesired behaviour. Personally, I'd advise against using this method without explicit support by the Makefile generator.
