If I remember correctly, 2.5 was supposed to have binascii.long2b() and
binascii.b2long() which would have converted a long integer to a 2.x
string and vv, offering access to the underlying PyLong_AsString() and
PyLong_FromString() functions.  According to my Python 2.5 distribution
and the documentation, it didn't make it.

Note that there exists a patch against some 2.3 for the struct module
that implements a typecode for allowing the packing and unpacking of
arbitrarily lengthed integers, also offering access to the underlying
PyLong functions.  This would likely need to be updated for the post-2.5
struct module, if its functionality is desired.
