Easier than you think: just pass -save-temps and look at the
timestamps on the files. (If nothing else is running, wall clock time
is good enough for such a benchmark.) If you want times for the
individual cc1 passes, "info gcc" M Invoking and look at the -dx
flags.

Motif style turns out to be an extreme case for C; the kernel and most
if not all BSD-supplied programs (I was about to say "most if not all
*useful* programs" but I'm being generous) are nowhere *near* that
cpp-intensive. (Only C++ tends to get you more cpp activity on
average, though Interviews is even an extreme case of that...)

And why don't *you* have the gcc sources? They are available, you know :-)
> I don't have numbers and must say i added a ":)" because i don't
Please try actually performing some experiments next time you have
such a proposal... it's less embarassing for everyone involved :-)
