287
288 Note that the meat of the test is contained in testcapi_long.h.
289 This is revolting, but delicate code duplication is worse: "almost
290 exactly the same" code is needed to test PY_LONG_LONG, but the ubiquitous
291 dependence on type names makes it impossible to use a parameterized
292 function. A giant macro would be even worse than this. A C++ template
293 would be perfect.
294
295 The "report an error" functions are deliberately not part of the #include
296 file: if the test fails, you can set a breakpoint in the appropriate
297 error function directly, and crawl back from there in the debugger.
