Hmm. ACPI already has that odd ACPI_USE_BUILTIN_STDARG case in
acgcc.h, which ends up using _exactly_ the same macros as the
<linux/stdarg.h> implementation does, and is basically exactly the
same "minimal stdarg".

Ok, so the macro argument names are different, and there are
whitespace differences, but semantically identical.

So maybe the ACPI code could drop one or the other in favor of the
identical macros?
