I was planning to just look at the extension, but as you say that is

People in that situation could just set DISTCC_CC=g++, unless they
also have files in the same project that are C, are called .c and need
to be built with gcc.  I hate to think what their Makefile must look

Yes, that would be OK.  Or maybe "distc++"?  It could either use
argv[0] tricks, or be the same program just with a slightly different
main().  It looks from the gcc manual like gcc uses the second
approach, and I think I prefer it too.

People might then ask for a --with-default-cc option so that you can,
if you want, build "m68k-linux-distcc".

And by that point perhaps "ln -s distcc gcc" was simpler after all...

Yes, if that works with your Makefiles etc it is far clearer.
