Is this a bug in node-gyp?

VS versions needed to build Node itself and native add-ons are different in Windows.

This used to be explicit in BUILDING.md, but with nodejs/node#14764 both versions became VS2015 so the text was unified. Perhaps we should split it again. I keep a list of versions in https://github.com/nodejs/build/blob/master/doc/windows-visualstudio-supported-versions.md, but it needs to be updated for recent versions.

We could drop support for building add-ons with VS2015, but we should try to do it in a semver major release.

@targos on that CI run, the tests passed on Windows 10, which is also using VS2015. I only see errors in Windows 2016, indicating that this is probably not an issue with V8 support.

The error appears to be caused a regression in cl.exe in VS2015. I can reproduce this with 19.00.24215.1 but not with 19.00.23506. Some build machines did not get the latest update of VS2015 automatically, thus CI passes.

@targos is V8 7.9 going to land in v13 or is it just being prepared for v14? It would be good to patch it to work with VS2015 if possible, but I need more time to look at this.

[targos]

I would like to land it in v13.x

[joaocgreis]

Moving the V8 discussion to nodejs/node#30020.

Perhaps we should consider removing support to build add-ons with VS2015 for Node v14.
