MS's nmake string handling capabilities are nonexistent. You can
'concatenate' variable contents, but breaking them down and iterating
over its 'words' is another world.
If you _really_ wish to experiment, you could try to process the
variable in a command block of some fake target. But each command is
executed in its own subshell, so you would loose variables set in it.
Divide and conquer does not apply here. It is easier to sum up.

Not yet. These days my time is quite limited. So this will progress on
the slow lane. Be patient, keep around, keep an eye on that file, and
we all will discuss things on this list.

Sure. Why not?

From inside a MS nmake makefile, being capable of setting a variable inside it?
I'm open to new ideas and improvements, of course!
