Need help testing 64-bit ports of audioop.c, imageop.c, rgbimgmodule.c

[Guido van Rossum]

As some of you might know, a few core extension modules for multimedia
operations don't work in 64-bit machines such as the DEC Alpha,
because they are coded with the assumption that a long is 4 bytes.
The affected modules are audioop.c, imageop.c, rgbimgmodule.c.

John Jorgensen kindly gave me some hints on how to fix them; I changed
his recipe a bit and it seems that the modules aren't any more broken
than before.

Of course, I hope that they are *less* broken, and to check this, I
need someone with a 64-bit machine to test them. Please let me know
if you can help me with this, and I'll send you the files.
