Have you tried AC_CHECK_DECLS instead?  You really are checking
whether sigsetjmp is declared and you can compile with it, not
whether it is a function and you can link with it.

But supposing that I wanted to pass around a pointer to it, that
wouldn't help much.

How do you pass around a pointer to an entity which is implemented
as a preprocessor macro?

My comment was in the context of a check for stat().

If you read my earlier comment, you should have guessed that I'd read
the comments on the opengroup webpage regarding setjmp().
