Description of problem: There seem be quite a number of reports of highlighting problems with Emacs font-lock-mode. However I haven't been able to reproduce any of them to date. This tracker is to follow the issue and hopefully gain some insight into the issue.
Ok, this probably doesn't apply to bug 145759 (since that is for makefile-mode) but I noticed this posting: http://lists.gnu.org/archive/html/help-gnu-emacs/2004-11/msg00431.html which suggests the font-lock problem may well be fixed in the latest cc-mode. So in the next build I'm updating cc-mode to the latest release to see if that helps with this problem. Could you please test that or try installing the latest cc-mode locally and see if it helps. (cc-mode is available at http://cc-mode.sourceforge.net/.)
emacs-21.4-5 will contain the updated cc-mode.
I closing this off based on feedback from bug 148977 and bug 150197. Thanks.
