???  Actually, you _can_.  You just can't link it into the GPL kernel
program.

There is nothing in the GPL that prevents a GPL compiler from producing non-GPL
code.
And LGPL can be statically linked against non-GPL compatible code.

So that means the OpenAFS _server_, which is user-space, can be built with GPL
GCC
and dynamically linked against LGPL GLibC.

But the OpenAFS _client_, which is kernel-space, cannot be statically linked
into
the GPL kernel program.

[ I believe there is an OpenAFS client that is GPL, missing various IBM code. ]
