Oh, I misread that. It's not really important anyway; being
incompatible with the GPL directly is just as bad.

[If this were valid, then the GPL wouldn't be incompatible with the
Artistic license either].

Anyway, here's an expanded form, written as a deductive sequence:

An abbreviated form of the so-called "viral" part of the GPL says that
everything you include in a GPLed work must be distributable under the
GPL. We interpret this as crossing library boundaries - vis. openssl
and GPLed code.

Therefore, in order to link a GPLed application with glibc, I need to
be able to distribute the source code to glibc under the GPL as well.

Note that the "system library" clause of the GPL:

"However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable."

does not apply, because the component does accompany the executable in
our case.

From this I can conclude that I need to be able to distribute any
given component of the glibc source code under the GPL.

So, I need to be able to distribute the sunrpc code under the GPL.

I cannot do this, because the restriction on distributing it "alone"
is in conflict with clause 6 of the GPL, which prohibits any further
retrictions.
