ok. When you're done, perhaps you'd consider writing up a FAQ entry or 
posting some notes for documentation? That would be much appreciated.

Nice, elegant hack to disable libsupc++, kudos. The #ifdefs in the header 
files are less elegant, but perhaps a more acceptable solution can be 
created when the sum total of your changes are finished.

You're flying pretty blind right here, but assuming the vendor runtime 
and header files work, well then. Your library should work too.

Aaah well. Glad you're having fun.
