For what it's worth, I still occasionally use icc for simple
tasks-- mainly as a reference for code generation, since it
produces reasonable output in many cases where gcc does not.
As I recall, making it work required minimal changes... possibly
just making sure __va_list gets defined in _types.h.  I have
the following in one of my trees, although this is obviously
not the right fix.
