The way I did it was by putting a 'punctuation syntax-table property on
each umatched string quote (and also each unmatched brace/bracket/paren).
The meat of this is in `c-neutralize-CPP-line' in cc-mode.el.

The essential precondition here is that C preprocessor lines live,
logically, in a different world from other statements, a bit like in
chess there are white-squared bishops and black-squared bishops.
