Marcel Taeumel uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-mt.3176.mcz
==================== Summary ====================
Name: VMMaker.oscog-mt.3176 Author: mt Time: 6 April 2022, 2:54:12.612017 pm UUID: e0dad7c2-84d4-c740-86d3-f270ffc43add Ancestors: VMMaker.oscog-mt.3175
Fixes v3.cog and v3.stack, which both do not specify the IMMUTABILITY option and thus there is no #define IMMUTABILITY in their generated interp.h, which will then make the generated sources for getCogVMFeatureFlags not compile.
Note that this seems to be a little bit different compared to, e.g., BIT_IDENTICAL_FLOATING_POINT. Not sure whether we want to discriminate between "defined" and "not defined" or "defined && 1" and "not defined || defined && !1". Seems to be mixed up at the moment. In any case, we must use a #cppIf:ifTrue:ifFalse: guard.
