Ok, clearly the Objective C++ compiler is getting invoked for you 
without having to use .mm, so I don't think it's necessary to modify the 
Makefile templates of Swarm.

One thing you might try is doing a cut and paste of one of the GCC 
invocations.   I was debugging yesterday using Heatbug.m.
Paste the gcc command that make runs for that file to the command line 
and then modify it to add "-E" and a redirect to another file.
As you probably know, what "-E" does is runs only the C preprocessor.   
In the output file you should see lots of lines that look like "# 
number".   If you send that to me I can probably figure out what's going 
on because I'll be able to compile it (or not) myself.
