Yes, that's easy to do. I would suggest however to keep libccdir as is, and
add a GFORTHCCPATH the way you want to. Public visible environment variables
controlling Gforth should be in uppercase and have a GFORTH in their name.

No complication. A path is also just a string (with '\0' as separating
character).
