But the version of djgpp.env that users have on their machines, which 
comes from djdev203.zip, does specify CPLUS_INCLUDE_PATH, and it points 
to lang/cxx, not lang/cxx-v3.  Won't this break C++ programs, especially 
if the users don't remove previous installation?

Yes, but how can we clean that without releasing a new djdev?

I think it's a good idea not only for DJGPP: if you invoke 
"/foo/bar/bz/cxxfilt --version" on Unix, it will print its full path as 
well.  I think this is ugly.  The intent of that message is to announce 
the _name_ of the program, not its full path.

Granted, this is a minor nuisance, so if you think it's not important, 
feel free to disregard.
