There were past discussions about this; please read them before
concluding that lrealpath is all we need.  My records seem to indicate
that a thread Re "fullname attribute for GDB/MI stack frames" in May
2005 on this list is one of them, but maybe there were more.  You will
find my critique of what lrealpath does on Windows in a message in
that thread I sent on May 29, and suggested ways to improve it in a
followup message on the same day.  I think if we are going to use
lrealpath, we should at least make its behavior consistent and correct
on all supported platforms, including native Windows (i.e. MinGW).
