/* Tests of PyLong_{As, From}{Unsigned,}Long(), and
   PyLong_{As, From}{Unsigned,}LongLong().

   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.
