[issue2636] Regexp 2.7 (modifications to current re 2.2.2)

issue2636-20101009.zip is a new version of the regex module.

It appears from a posting in python-list and a closer look at the docs that string positions in the 're' module are limited to 32 bits, even on 64-bit builds. I think it's because of things like:

    Py_BuildValue("i", ...)

where 'i' indicates the size of a C int, which, at least in Windows compilers, is 32-bits in both 32-bit and 64-bit builds.

The regex module shared the same problem. I've changed such code to:

    Py_BuildValue("n", ...)

and so forth, which indicates Py_ssize_t.

Unfortunately I'm not able to confirm myself that this will fix the problem on 64 bits.
