That part I have mostly ready (worked as part of a rebase of the meson tree
sometime last weekend). It's trawling through the docs, the msvc build scripts
and some plpython C code that's a bit more work...

Attached the state as I have in the meson tree. Will split out the configure
test tomorrow. Might or might get through the msvc scripts and docs as well.
