Eli, this is inconsistent with the rest of the world.  In the rest of
the world, realpath() and canonicalize_file_name() call getcwd() (or
the operating system's equivalent function).  Can you explain to us why
it is correct for other OSes to do this resolution in xfullpath (or
wherever else), and for DJGPP not to?

It doesn't.  It should.  More precisely, gdb_realpath should be removed
and replaced with libiberty's lrealpath().  I was under the impression
that I had done this when I added the function to libiberty, but
obviously I forgot.
