The only reason I can think of is that this was probably once
changed due to linking issues?  AFAICS, the swift headers
are for C, so I dont see a reason why CXX is used here.

Hmm?  Did you set CXX to gcc-4.4?

Yes, using gcc-4.4 instead of g++-4.4 work just fine, however, I
haven't tested if it actually works at runtime now...

Dave, do you remember why we put in CXX in that makefile?
If there is no special reason, its probably a bug and should be changed
to CC.
