This is a point, but I'd consider it unlikely.  Since the ability to read
user-provided #include files needs to be present, it would be extra effort
to provide a different way to handle standard #includes.  And even if the
compiler did something like this, say like the pre-compiled headers provided
in the Manx C compiler on the Amiga, I'd be surprised if the originals weren't
provided as well.

This is a more interesting point, and one I hadn't considered.  Ideally, there
would be some way to specify dynamically-determined things directly in the
#include file, but I have no idea how this might be done.  Perhaps <default.h>
could be considered the, ah, default set of options that could be over-ridden
by command-line flags?  But then we're back to where we started....  Hmmmm...
