Can anyone find a system on which this doesn't work?

Dozens of them.  Acat is taking variable-length argument lists, which
is the kiss of death for portability.  Declaring lots of parameters
and then using them in order is highly machine-dependent; it makes
major assumptions about how the argument list is laid out in memory.
Using <varargs.h> would be a lot better, but even that is not perfect.
There exist machines on which <varargs.h> is unimplementable.
