What do you mean by "trip up"?  Sounds like a plain bug to me: any
normal program may have such definitions (tho it depends on how "tripped
up" it gets; it's normal for cc-mode to behave suboptimally when
encountering unknown macros and type annotations, but it should try to
be robust in such circumstances).

Similar needs arise for large projects (e.g. DEFUN and friends in
Emacs's C code), IIUC, right?

So I think we would want to move such project/system-specific outside
cc-langs.el so users can (load "cc-microsoft") or (load "cc-linux") or
(load "cc-emacs").  Tho, loading a file is the wrong interface, so maybe
it can live in cc-langs.el but it should be inside a function so you
could activate it with (cc-enable-microsoft-keywords), or maybe a minor
mode (cc-microsoft-keywords-mode 1), tho turning it off might not be
that important.
The point is to make it modular so it's easy for people to add support
for particular projects.
