  You confused me by referring to $cdir, which i didn't think was the same
thing  as the path embedded in the runtime file (else what would be the
point in concatenating it to itself?).  IIUIC, $cdir is just a user-level
convenience variable that you can set however suits you.

  Well, the new source path features are only in mainline (CVS), not in
either the 6.1 nor the 6.2 release branch.  Seems like they gave you
documentation from a more up-to-date version of gdb than the actual binary
they gave you!

  Well, you may _very_ well be able to work around it with a mount point or
symlink or two.

  Ummm..... you do have to use the same kind of cross objdump as the cross
compiler and cross debugger, you know.....    [guess it is getting late!]

Can't think of a witty .sigline today....
