Line 418: A struct sequence that holds information about Python's
I don't think the sequence interface is really important here. There
should be a way to easily define regular struct-like classes (with no
sequence interface). Perhaps structseq could be modified to drop
sequence interface, and new structseqs should turn it off usually.

Merge the comments into a single on. There is no need to preserve the
evolution of the code in the comment structure.

Why not PyLong_FromLongLong if available (no special case if not)?

Line 318: #define PY_UINT64_T unsigned __int64
I think this should use PY_LONG_LONG, to support MingW32; likewise,
__int32 shouldn't be used, as it is MSC specific

Line 160: w_long((long)(Py_SIZE(ob) > 0 ? l : -l), p);
This needs to deal with overflow (sizeof(size_t) > sizeof(long))

Line 540: if (n < -INT_MAX || n > INT_MAX)
I think this is obsolete now; longs can have up to ssize_t_max digits.

I'm skeptical (-0) that we really need to have such a configure option.

Likewise, this needs to be preserved.
