Those tests failed on 32-bit Emacs configured --without-wide-int, as 1+ silently wraps around whereas mod-test-sum signals an integer overflow. Plus, on a 32-bit-only Emacs #x20000000 evaluates to a floating-point number -- a flaw in Emacs, but is probably not something we can fix during a feature freeze. Sorry, I hadn't realized the points of those tests, and thought my replacements were testing the same thing. I just now brought those tests back and ported them to 32-bit-only Emacs.
