Doesn't pwd.h include a declaration for getpwent(3)?

%
%  setpwent("/etc/passwd");

At least in BSD 4.2 setpwent(3) doesn't take any arguments, so this
should be

	setpwent();

%  while ((pwd = getpwent()) != 0)
%   {
%    printf("\n", pwd->pw_name);

Try

	printf ("%s\n", pwd->pw_name);

%    fflush(stdout);
%   }
%  endpwent("/etc/passwd");

Likewise, endpwent(3) doesn't take any arguments either.
