Crash when running any ape on Windows 7

[G4Vi]

None of the test executables appear to run on Windows 7 now.

Used make -j4 MODE= o//test/libc/calls to build.

I don't think I can support it anymore. My Windows 7 VM croaked a few months ago. It wasn't very pleasant while it was working either, because even though I paid for a license, once Win7 hit EOL, Microsoft reprogramed the VM to show me all these invasive warnings about piracy. I can't support what I can't test. Windows 7 has issues like not supporting a 64-bit address space, and needing exponential backoff when talking to many APIs. If there was an easy way to run Windows 7 and SSH into it without being treated like a criminal, then I'd be happy to support it. Otherwise we might want to bump the support vector up to a more recent version.

For reference, here's when I removed win7 from the test fleet. https://github.com/jart/cosmopolitan/commit/13c1c45075cb2a12e0624d392da9382cca040e4b

FWIW, it still works for me on Windows 8.1

Thank you for reporting in @pkulchenko ! That's the one I was really worried about.

I would have tested on my win 7 machine, but it's unfortunately running 32bit version ;(

I don't think I can support it anymore.

I guess Windows 7 is pretty legacy and sounds difficult to support. I never moved my desktop up after having constant issues with Windows 10 updates breaking my dual boot and undoing my registry fixes on my laptop.

I'm fine with bumping the Windows support vector up, but I'd prefer code still did it's best to support older Windows in-case someone has time to look into it and fix this though I realize it's impossible to know without being able to test it.

@G4Vi I've officially sunset our Windows 7 support. While it's gone, it's not forgotten. Cosmopolitan v2.0 should still work. If you wish it, we can create a v2 branch. You can then send us PRs backporting any functionality you need, and I'll issue releases for them. The same goes for anyone else reading. I hope this will be a satisfactory outcome to this issue. Thanks for the report!
