Yes. Sorry, I've been very slow answering. The canonical address for
CC Mode problems is <address@hidden>.

The face for "foo" is deliberately set to c-reference-face-name (At
cc-fonts.el L667 (in (c-lang-defconst c-basic-matchers-before ....)).
c-reference-face-name is defined (earlier on in the file) as
c-label-face-name, which (in its turn) becomes font-lock-constant-face.
So this is quite deliberate. I don't assert it's "right", for whatever
value of "right". Maybe this could be described more clearly in the CC
Mode manual (on page "Faces").

What is this, syntactically? Is it valid C++?

(See above.)

:-) The fix, if such is needed, would be to redefine (defconst
c-reference-face ...) at cc-fonts.el L145.
