I thought msvc supported _Static_assert as well, but after a short search it seems I misremembered and it only supports static_assert from C++11 (which is plausible, because I've worked on a C++11 project which was ported to windows ). I don't know how C and C++ compilation modes are different in msvc. I really don't understand why C and C++ standard development isn't coordinated more... They seem to come up with annoying incompatibilities all the time. > I'm fairly sure there are already a few cases of Asserts on > compile-time-constant expressions, so I made sure that there was a layer > allowing access to _Static_assert without the type-compatibility code. > I didn't go looking for anything to convert, but I think there's some > in the shared memory initialization code. Definitely a sensible goal. I wasn't really sure how well the idea would be received after I asked before and only heard echoes of my excitement and didn't want to spend too much time on it...
