Right. Basically, .jam files don't have direct access to path-constants --
because path constants for Jamfiles and generally, location of .jam files
do not matter. I don't want any path constant to propagate into gcc.jam ;-)

Depending on what you're trying to do you can either:

1. Pass constants to your module explicitly, calling some rule.

2. Pass the name of Jamfile module to your module, and then use 'peek'.

3. Obtain name of Jamfile module from result of [ project.current ]
and again use 'peek'
