Careful. error.c is (mostly) synced upstream with glibc (right now, all
but the comments and a couple of #include order issues), but this would
widen the gap. As it is, error.c already has a check inside _LIBC that
does exactly this; since glibc provides program_invocation_name already
set to the right value. Also, how would this interact with the progname
module?
Maybe a better approach would be to make argp and progname play nicely;
and on glibc systems, use the existing program_invocation_name. It may
also be worth trying to push a change upstream to glibc to use
program_invocation_name instead of program_name, and simplify error.c.
