Fair point. It's not just about fixing windows or needing Windows-specific
*features*, it's about making it harder to develop things because of
Windows. I've seen that myself.

Yeah, you're right. He's not the only one either.
I was reacting to the original post, and TBH didn't think it through. The
commit logs suggest there's a decent amount of work that goes in, and I'm
sure a lot of it isn't visible when just looking for 'windows', 'win32',
'msvc', etc.
Even the build system affects people who don't use it, if they're adding
features. I recently backported a bunch of 9.3 functionality to 9.1, and in
the process simply stripped out all the Windows build system changes as
"meh, too hard, don't care".
So yeah. I casually handwaved away a lot of work that's not highly visible,
but still happens and is important, and was wrong to do so. I've done a bit
on Windows myself but didn't fully recognise the burden support for it
places on patches to core infrastructure and on committers.
