CPP outputs wrong number of newlines sometimes

Hi Jamie,

Could you send the bugs to gcc-bugs?

Thanks for spotting that.

Probably.  I'd rather not scan the string / comment again,
particularly if we're moving towards multibyte char support.  It might
be better to somehow record the number of lines involved when lexing
these tokens.  That would be easy (just the difference between
buffer->lineno before and after the relevant function call); finding
the place to store that info would be harder.  Don't you just love GNU
extensions? <g>

Maybe you could get the paperwork done anyway.  I'm sure it'd be
useful for the future.

Thanks,

Neil.
