An obvious alternative is to do "2" -> "[23]" *and* update the else to an explicit check for "1", *and* add an else that fails the build when it sees "4" and other unknown ones. I do not know how compatible MSYS2 runtime v4.x will be with the settings the part inside the ifneq() we see here protects, but you probably do, so I think this would be good enough. The only case that makes any difference is when v4.x _mostly_ satisifies but slightly differs, affecting the built binary in a subtle way that is not discovered right away. But in such a case, the more cautious "fail on '4' that we do not recognize" will not help much, as the first reaction after seeing the error would be to copy the settings that used to be OK with v2.x and v3.x anyway (which is what is being done here---we start with the assumption that the support needed for v3.x is largely the same as v2.x). Will queue directly on top of... 'maint'? 'master'? Let's say 'maint' and merge that up to 'master'.
