[Python-Dev] Python should be easily compilable on Windows with MinGW

[Andrew Barnert]

One alternative to consider is using Cygwin. A complete Cygwin environment, including a GCC toolchain, is pretty small. And it can build a *nix-style CPython that works inside the Cygwin environment. That may not be sufficient for a lot of uses, but for your purpose, it should be.

Another alternative, as crazy as it may sound, is to get an AWS-Free-Tier EC2 instance and develop on that.

Or, of course, buy an ancient used laptop and install linux natively.

Obviously none of these are ideal, but they may still be better for you than waiting for a complete MinGW port of Python or a smaller MSVC toolchain.
