    Hi Andreas :)

    There's an easier way. Edit gcc/ and search for echo..
    then change gcc to (eg) tgcc or egcc or whatever. The same can be
    done in cp/ and f/ for c++ and fortran. The
    only thing to watch out for is that gcc-2.7.x cannot be configured
    to the same directory (i[456]86-blah) as any of the new breed.

    Also, if you want to have a g++ that is using the 2.7.x lib/headers,
    you need to install these into the configuration directory..
    /usr/i486-blah/lib and include. Then, you can build either way. The
    same holds for cross-compilers.

    This info is intended for folks who may not know how to deal with
    multiple devel systems.. not for your consumption Andreas :)

    This cannot be stressed enough. Same for the unadvisability of compiling
    kernel-2.0.x with a new-breed compiler.. despite 'works for me' reports.
