Summary: test_getargs2 failing

Initial Comment:
Adding this just so it doesn't fall by the roadside (it's been discussed 
on python-dev): test_getargs2 is currently failing, at least on MacOSX.

Um, I think I found the reason. test_getargs2 uses
getargs_ul (in _testcapimodule.c) to call
PyArg_ParseTuple(), and this always passes a pointer to an
unsigned long, even for H and B format codes. On little
endian machines casting this pointer into a unsigned short
pointer works ok, but not on big endian machines. Makes sense?

Strange, since 196608 == 0x30000, and 50331648 == 0x3000000.
Even stranger (to me) is that the test for upper case i
works, and it uses nearly the same code.

Does it help the test_H case to change line 485 of getargs.c
from 'long ival;' to 'unsigned short ival;', but I'm only
guessing?

Yes, I still have the problem. The test output is attached.

This is fixed on all the snake-farm machines AFAIK.  Jack,
are you still having the problems?

This is failling on several other architectures in the snake
farm:  http://www.lysator.liu.se/xenofarm/python/latest.html
