Re: Guile 64-bit Windows support, redux

OK. This patchset does not result in a functional build on any of the Win32
VMs I've tested.  It seems necessary but not sufficient.  I feel like there needs to be a few more patches that should have been attached.  I could fairly easily
tweak it into shape, but, I'd rather make sure I've got the full story first.

For reference, I started with a recent main and applied 6 patches I found in
the history of this email-chain.

- Fix lightening x86_64 Windows calling convention
- Store hashes as uintptr_t
- Decouple scm_t_inum from long datatype
- Rename functions that should accept scm_t_inum
- scm_integer_modulo_expt_nnn: Refactor to use scm_to_mpz
- scm_i_divide2double: Refactor to use scm_to_mpz

If someone wants to point me to a complete source tarball
to diff with main or some other additional source of information,
I can continue my evaluation.    Else, I can use these patches along
with my own patchset to complete this work.
