Mike,

I fought with this a few months ago and ended up commiting:

   http://trac.osgeo.org/gdal/changeset/14323

Unfortunately, it appears I didn't write up anything in the wiki or a ticket
about the issue so now I can't recall all the details.  But basically, yes,
it seems like it is necessary for the bindings to be generated with -nopgcpp
and this really ought to be in the makefiles used to run swig.

Perhaps you could file a ticket on the issue with your findings, and a pointer
to r14323 suggesting the needed additional changes.

I have a vague recollection this issue may have related to specific versions
of swig.

PS. you may also want to contribute to one or both of:
