Bug#410466: Stupid lp64 bug - undeclared func returns int and sizeof (int) < sizeof (char*)

[John Hughes <john@Calva.COM>]

Bug 410466 happens on lp64 platforms (e.g. "amd64").

Code is:

181         snprintf(id, sizeof(id), "%d.%d.%d.%s", (int) getuid(),
(int) getpid(), (int) time(0), getmyname());

But "getmyname()" is not defined, so defaults to returning int.

However sizeof (char*) > sizeof (int) so 32 bits of the address are
thrown away.

Bang.

Q&D fix:
