Can't get this to work with SIGTERM on Windows

[robx]

I was trying to use the signal package to handle SIGTERM in a cross-platform way in the context of this cabal pull request: haskell/cabal#7921.

It turns out that apparently, GHC's Windows runtime doesn't deal with whatever taskkill sends meaningfully, and installing a SIGTERM handler with this package has no effect on Windows. Looking further, it seems that this package simply provides a thin wrapper around mingw's signal.h, which appears to not actually do much at all: https://sourceforge.net/p/mingw/mailman/message/16209215/

So I guess my questions are:

• is there a way to use this package to meaningfully handle SIGTERM?
• if not, in what scenario might this package actually be useful?

Ditch mingw and use ucrt64.
