Nice hint :-D  Thank you.  I guess that fulfils my requirement.

However, I'm not an expert on the (c) tricks so to avoid any problems,
I just explain the distribution process I'll use and I'll be more than
grateful if someone could confirm that it doesn't conflict with GPL.

The process: I make an image of the sources using 'cross'.  I put the
image (with no source) on a CD along with Gforth binaries and a GPL
copyright text.  I sell the CD at price X.
