Suggestion for sets_cc0_p problem

[Bernd Schmidt]

Here's a suggestion how to fix the sets_cc0_p problem properly.  As the
function only calls abort if [! HAVE_cc0], we might as well turn the
run-time error into a link-time error by ifdeffing the function out.

Bernd

	* jump.c (sets_cc0_p): Compile only if HAVE_cc0.
