Any reason for this? There's certainly more important things than opening this palette of cans of worms...

The MinGW support is not stable and thus cannot not be used for release builds (see the simplecpp issues). First we need sort out everything on the simplecpp side and make the simplecpp CI complete. After that all the CI improvements regarding MinGW (and Cygwin) also need to be applied to Cppcheck which will probably unearth more issues.

Also the MinGW builds in Cppcheck never went through the full CI sweep and only used very basic checks. So after the CI has been adjusted with the simplecpp improvements we need to apply the full CI sweep to MinGW as well.

Performance. I have seen ~3 times faster cppcheck analysis in selfchecks.
