Uhm, yeah, well... C++ is not supported.  :)  Although it's conceivable it
might work for VERY VERY VERY simple C++ programs (like a single class, no
standard headers), exception support has not been implemented at all, and
there are probably lots of other things that don't work.  In general, I
haven't even tried to use the C++ compiler for more than a year (and back
then it was far from working).

There isn't anything precluding getting the G++ frontend to work (and it's
probably not that hard, baring exception support), but I don't have the
time to work on it now.  The C++ frontend is definately on my TODO list,
although it probably won't be working well enough for use before 426 is
over.  :(

Perhaps after Thanksgiving I can give it a try and see how things stand...

btw, bitfields are currently broken in the GCC frontend as well, they just
haven't been high enough priority to fix yet.  My LLVM TODO list is very
long.  :)
