Again, I'm not too warm on this.
Remember, the idea is for autoconf to perform a feature based test: is
feature XYZ supported? In the case of the above, the feature question
is: does the system have a useable sigsetjmp()? Unfortunatly, the test
currently asks: does the system have anything looking like sigsetjmp(),
working or not? :-) I think Keith's original patch is the correct fix.
It refines the test so that, for cygwin, it reports back ``no
sigsetjmp()'' is not there (or is broken).
