Yes, apple-gcc-4.2.  Thanks for clarifying...I've been a bit puzzled 
about the differences of the various [blah]-gcc-42's.

Understood; when I get some time, I'll try to come back to this.  A 
quick search suggests this is the one and only '*.mm' file in the 
entire code base.  I suppose it is a case of adding an exception for 
it...somewhere.  Right now, I need to test with Michael's newly 
released qt4-mac @4.8.2, update to a more recent MythTV commit, fix 
some more hard-coded prefixes, write some docs, ...
