Note that the meat of the test is contained in testcapi_long.h.
This is revolting, but delicate code duplication is worse: "almost
exactly the same" code is needed to test long long, but the ubiquitous
dependence on type names makes it impossible to use a parameterized
function. A giant macro would be even worse than this. A C++ template
would be perfect.
The "report an error" functions are deliberately not part of the #include
file: if the test fails, you can set a breakpoint in the appropriate
error function directly, and crawl back from there in the debugger.
