I've been wondering if a workable alternative would be to make the
point motion functions look at a variable.  If the variable is set,
they ignore text with a certain property.

Suppose that we set the (hypothetical) text property `language' to
`c' on all the C bits, and then we let-bind the variable to the value
`c'.  Then all point motion commands would skip all text where the
text property language is not set to c.  So backward-char, for
example, would skip all that text.

This *might* cause the C mode syntax parsing functions to do the
right thing out of the box, since they can't look at the non-C parts
anymore.  But I don't know if it really works, it's just an idea.
