--with-gxx-include-dir specifies the directory where g++ header files
should be installed and where the new compiler will look for them.

--with-local-prefix is needed by very few folks.  If you don't know
what it is, then you probably don't need it :-)

You could just use --prefix=/usr/gnu if you wanted everything to live
under /usr/gnu.

That would force the binaries, libraries, include files, etc etc to
all be installed under /usr/gnu.
