Thanks for the reply. :)

Yes, I asked the SWIG mailing list as well.  But I was wondering if 
perhaps it was a bug in the CMake output, since the code in the .i file 
doesn't compile at all.  My main question (on this mailing list) wasn't so 
much "Can somebody fix this?" as "Has anybody seen such a problem before?"

Regardless, I sent the *complete* set of error messages.  There's just 
this single syntax error.

Thank you,
Adam
