Re: [orium69@gmail.com: Bug in emacs 22.1.1 (cosmetic bug)]

Hi, Diogo and Richard!

ACK!

In a C file, write this:

> #warning for isn't a keyword here

The fontification goes haywire.

The cause of the bug was the apostrophe in "isn't", which was being
handled as an unbalanced string quote.

This bug was actually quite profound; unbalanced parens/brackets/braces
also caused syntactic havoc in other ways too.

I have now committed a fix to the EMACS_22 branch at Savannah.  I'm
going to commit it to the trunk too, ASAP.

Diogo, thanks very much indeed for reporting this bug!  How would you
prefer to get the fix?  If you're familiar with the Emacs repository at
savannah.gnu.org, you could download the latest versions of the CC Mode
lisp files (..../lisp/progmodes/cc-*.el).  Or I could sent you an up to
date set of these by email.  Please let me know!

However you get them, please make sure that cc-defs.el is byte-compiled
first, followed by cc-langs.el.  The other files may then be
byte-compiled in any order.
