It is currently busy building the 5/rtems-sparc build set (without GDB) in a mingw64 shell. Is a build in the msys shell something useful/supported?

Yes, we have valid users. Plus building on Windows is valid for the same reasons we build from source on all hosts maybe more so.

If I install msys/mingw I get an msys, mingw32 and mingw64 shell. They are all somewhat different. Are all of them supposed to be supported?

They are different in a subtle way, they set different paths so you get a different set of native executables and DLLs in your path. Run:

 `set | grep ^PATH`

in each instance and compare. On top of that the mingw native tools are specifically named, something I completely agree with.

MSYS2 is well thought out, the pacmac tools is great. Like cygwin a rolling release makes baselining for deployment or a product hard.
Yes, but should RTEMS build on all three shells? Which one is recommended?
