I have spoken to Xoreax (the makers of Incredibuild) and they are
interested but unable to assist, as the problem is inside make and not
their product. The logical step then was to make my own debug version of
make from the source, but I cannot get the same behaviour from a locally
compiled make (using latest CVS as downloaded from Savannah) as I do
with the version from the cmake website.

will it?)

The fix allowed for C:/ to be a valid path.  It had nothing to do with 
-j.  Current CVS should have the fix, I don't have a date.

It was built as cygwin.

You might want to look at this:

http://sites.google.com/a/rwalker.com/cygwin/make-381-DOS

It has the source as well.

That is a cygwin issue.
