Sounds like a dumb error output rather than a dumb memcpy()
prototype. (Unless... is this the libc memcpy() or the kernel
memcpy()? The kernel might have good reason to have a different
prototype based on the MACH-ness of Darwin.)

What's the C compiler involved here?

Doubtful. But possible.

Not everywhere. Look into the machine-dependent code on anything
that runs on a PowerPC some time.

Try map[nmap].alias = (char *) memcpy (&...);

... where, I assume, you're using gcc?

gcc accepts a lot of things that are not, properly ANSI C. That
doesn't make them any less Wrong.
