Accusations, accusations, always accusations

[Richard Stallman]

    Is GTK part of the GNU project?  I thought it was part of the GIMP
    project.

GIMP is part of the GNU Project too.

    This would include any embedded system, anything written exclusively
    for a GUI, any daemon, anything which can use sfio (e.g. Perl),
    anything written in a language other than C...

These programs may not use printf, but they surely use libc.
Which means, in GNU/Linux, that they are using GNU libc.

    In particular, the ucLinux project isn't interested in distributing
    any of these tools since they're not important to have on your Palm
    Pilot.

It sounds like they are making a system quite different from the usual
"Linux" system.  Perhaps the only thing the two have in common is the
kernel.

If they are that different, calling the usual systems GNU/Linux could
be a good way to make it clear how different they are.
