It's no worse than if you try using any of the other dozens of names
unreserved in ISO C like "alloca", "bzero", "gettext" or "fork" as an
identifier.

These builtins are defined specifically as extensions and go away with
--std=c89.  You can also disable them individually with
e.g. --no-builtin-stpncpy if they get in the way.
