Actually, the libcc API has stabilized, and the need to recompile the libcc 
interfaces for every Gforth snapshot isn't there anymore.

So it makes sense to install programs with precompiled libcc-named files, and 
keep them separate from the Gforth directory, which is updated every week or 
so (if they use my snapshot Debian repository).

As I can see the request, for third-party programs using Gforth as Forth 
engine, who want to install their files in a different directory.   The source 
files installed in some other directory can be dealt with GFORTHPATH, the 
libcc-named files installed not — they have to go to a version specific Gforth 
directory.

We can also discuss if we add the $prefix/lib/.../site-forth path into the 
libcc-path by default.
