pathnames do not resolve if they include symbolically linked directory components

hello;

i was looking to port something from mcl/digitool and am wondering 
about pathname support.
should i expect symbolic links / aliases to work?
it does not appear that they do.

files for which translate-logical-pathname should resolve to a filename 
end up with a pathname which still reflects a symbolically linked 
directory. both probefile and truename fail for these files.
