I guess what I should have asked is how are the constructors and destructors
called without the CRT? My understanding, and it could be quite easily
flawed, is that without the startup code for the runtime, constructors and
destructors aren't called. But if they can be called in a _ATL_MIN_CRT
build, then something has to be doing the leg work.
