Does a test already exist that checks for if the >> operator in C does
arithmetic shift? Section 5.5.1 "Portability of C Functions" of the
manual mentions the problem, but lists nothing about a way of
determining actual behavior. Seems that it would simple enough that I
thought I would ask before

Yes. That works and something similar is the basis for the code I
posted. Autoconf doesn't have to be dragged into it, but
