RC_PARAMS doesn't seem to work on windows 10 powershell

[ChopsII]

After some digging around, it seems that _dupenv_s, and the entire concept of accessing a programs own environment variables, have been done away with in UWP.

https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/dupenv-s-wdupenv-s?view=vs-2019

Suggest to provide a file-based alternative configuration method?

cmd still works fine, however

would changing out _dupenv_s to std::getenv fix the issue? note that the main dev doesn't really work on RC anymore (though he might accept pull requests?).
