[PATCH 0/3] MR5915: include: Tweak atexit and cpuid declarations, guard DECLSPEC_UUID definition.

[Rémi Bernon]

IIUC atexit isn't exported by ucrtbase, but still exists (maybe as a builtin) and is resolved to a module-local symbol which can be used to register functions executed on module process detach. It is called implicitly by C++ compilers to register static destructors.
