On looking at this I still can't see how it's not broken. You are
effectively assuming that getopt_long.c must define those variables.
But surely getopt_long.c should be assuming that getopt.c defines them.
Aren't we likely to end up with the situation that everyone is
extern'ing them?
What appears to me to be happening is that Solaris' linker is failing to
merge global variable definitions when it should (must) do so. We need
to find out why rather than solve it with a patch that will certainly
break other platforms.
If you can't come up with a real solution, we might have to do this
with "#ifndef SOLARIS" or something similar.
