Proposal

Stop supporting MJIT on MinGW from Ruby 3.2

Motivation

Compilers on MinGW behave weirdly and MinGW-specific C code is sometimes required as a workaround. Despite the high maintenance cost, nobody seems to be using MJIT on MinGW.

Background

• I installed Ruby 3.1 with RubyInstaller2, which I believe is the most popular method to install MinGW Ruby, and MJIT didn't work in that environment.
• MinGW is known to be very slow at compiling C code. It's improbable that the architecture of MJIT performs well on that platform.
• In other platforms, compiling an MJIT-generated .c file to a .so file works fine, but it fails on MinGW without any error message. So we have to compile .c to .o first and then build a .so file, just for MinGW.
