It might be better like this:
main(int argc, char **argv, char **envp)
{
if (argc > 0)
argv[0] = (**argv == '-') ? "-zsh" : "zsh";
execve("/usr/local/bin/zsh", argv, envp);
_exit(1);
}
That handles login shells, which Zefram's doesn't.

The only reasonable runtime fix I can think of would be an environment
variable to specify the emulation mode, which would take precedence over
argv[0]. That would potentially also solve the argv[0]="su" problem for
which I posted a patch some months ago.
An option to compile out argv[0]-based emulation would be possible, but
didn't receive an enthusiastic response the last time it was suggested.
