Thanks, John, for suggesting the fullfile command, and Matthias, for
suggesting filesep in a subsequent post.  I wasn't aware of these
functions until you mentioned them.  (Seems the WaveLab crew didn't know
of them either.)

Using fullfile would make for a clean solution, but would have required
more substantial changes because the original file concatenates the
directories and path explicitly.  For the dual reasons of laziness and
desire to leave the structure of the original as intact as possible, I
simply modified the existing definitions of variables to use filesep and
pathsep in place of system-specific, hard-coded values.  The modified
file is attached.

Ran the script and successfully added Wavelab directories to the path on
Ubuntu 8.04 (Octave 3.0.0) and Windows XP (Octave 3.0.0 MSVC).
