No, they don't.  I accept that you care about compiler speed.  What
most people care about is not speed but compilation times, and as
long as the times are small enough they don't worry about it.

Another difference may be relevant here.  Based on other comments of
yours I have the impression that you frequently invoke compilations
interactively.  A lot of people never do that (or do it only very
rarely).  In a project I am working on now I do builds often,
including full builds where every .c file is recompiled.  But all
the compilation times together are only a small fraction of the
total, because doing a build includes lots of other steps, including
running regression tests.  Even if the total compilation time were
zero the build process wouldn't be appreciably shorter.

I understand that you care about compiler speed, and that's fine
with me;  more power to you.  Why do you find it so hard to accept
that lots of other people have different views than you do, and
those people are not all stupid?  Do you really consider yourself
the only smart person in the room?
