We already have a max path number, why use a different one?
It's max path for Windows, not Linux (thus the "W_" prefix) :)
Maybe changing it to WIN_MAX_PATH or such will make it better?

These are all ripe for a simple search/replace in your editor before you
do your next version :)
I've actually attempted that, and reverted that change, mostly because
the whole 'handle' thing became very confusing.
Note that we have a few 'handles', each with a different size, and thus
calling get_something_something_handle() type of functions becase very
confusing since it's not clear what handle we're working with in that
case.
With regards to the rest, I wanted to leave stuff like 'winbool' to
document the expected ABI between the Windows and Linux side of things.
Ideally it would be 'bool' or 'u8', but as you see we had to use 'u32'
here which I feel lessens our ability to have the code document itself.
I don't feel too strongly against doing the conversion, and I won't
object to doing it if you do, but just be aware that I've tried it and
preferred to go back (even though our coding style doesn't like this) :)
