emacs C/C++ comments

[Drosos Kourounis]

Dear Developers,
thank you very much for developing emacs for all of us.
There is a minor problems with emacs commenting out.
When for instance one uses the following symbol for comments
//
then everything is fine! Unfortunately this is not what happens
when one want's to use for convenience the C style of comments
/*
*/

Two "bad" things happen then!
1) Comments do take some time to change color
2) The commented part of the code itself may or
     may not change its color in a big part of it depending
    how big the part of the code which is commented out is!

I am sure that you have encountered this problems yourselfs!
Is there any work out?

Thanks in advance!
Drosos.

Emacs doesn't recalculate the coloring of the entire buffer
immediately after each key stroke for obvious reasons.

Not sure if this is an Emacs problem.  You are aware that C comments
don't nest?  Using #if[def] ... #endif clauses if you want to deactivate
longer parts of your code is the preferred method.
