As Diane suggested, SOURCE_GRIST it could be anything.. to make it
easier why not just make it the same as the library for that set of
sources if its enough to distinguish between sources - it doesn't have
to equal the default value of the "current directory". i.e.

rule FrameworkObjects
   local SOURCE_GRIST = $(<) ;
   return [ FGristFiles $(>:S=$(SUFOBJ)) ] ;

Now set SOURCE_GRIST in the component/framework's jamfiles to the name
of the library.
