Perhaps in Ada parsing only takes microseconds.  In most of the C-family
languages with which I am familiar, parsing takes the majority of the time.

My only point here is that precompiled headers /do/ make a difference and
/will/ be a very big win once they are implemented, especially for C++.
The current 10x-20x lossage on PPC is painful to hear about, and I don't
even use that platform.  :-)
