Never mind.  Although I still don't know how to wrap functions properly
in octave, it turns out that the above gcd example lead me astray, and
_both_ the specific namespace (e.g., plplot_octave.plinit()) and dropped
namespace (e.g., plinit()) are available with the swig-generated
octave bindings so function wrapping is not required (for this purpose).

Once I understood that accessing the dropped namespace was not an
issue, two additional real issues had to be sorted out (revisions
11389 and 11390) and the result is x10c.m "just works" on Linux with
the swig-generated interface.  That good result fundamentally
validates this whole idea.

The current status is I am expanding the list of octave examples to be
tested to include the few more beyond standard example 10 which do not
use array arguments.  Once those additional examples give good results
on Linux, then I will try a wine test, and assuming that works, the
next step is to introduce more typemaps dealing with arrays, etc., so
that the tested examples can be expanded to the full list of both "x"
and "p" octave examples.
