Try using CC='distcc g++' or add -xc++ to the compiler options.

In general I think running

  gcc -c thing.cc

will compile it correctly, because the filename (and then the
explicitly given language option) have higher priority than the name
you used for the compiler.  The only exception as I recall, is if you
want a file thing.c compiled as C++ without giving an option to say
so.

If distcc is run as, say

  distcc -o prog thing.o wibble.o

how's it supposed to know you want them linked as C++, and if run as

  distcc -c thing.c

how's it supposed to know you want it compiled as C++?
