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).
