PS: The permutations documented in the previous MM were building for win32-x86-mingw. I can observe also that permutation 8 works perfectly for win32-x86. I didn't benefit from the experience of attempting all of the other permutations for win32-x86, but I know that at least some of them don`t work.

A similar comment applies. 

The win32-x86 target builds, but the currently supplied gnu make in mingw doesn't seem to work unless I add "SHELL = cmd.exe" to CONFIG.win32-x86.Common. I can't say for certain if this is ending up with a strange hybrid of mingw32-make 3.82 and msys make.exe 3.81, but msys _must_ be in the path when it works so we can make some guesses. 

Is there an EPICS approved/recommended source for installing gnu make 3.81 on windows?
