IMCC bug: Sub names are not labels?

[Luke Palmer]

The following doesn't work:

    .sub _main
        newsub $P0, Sub, _foo
        invokecc $P0
        end
    .end

    .sub _foo
        # ...
    .end

Indeed, it can be done by using C<addr> and C<set>, but shouldn't sub
names be considered global labels, too?
