Plop, I need a measure counter for the score I'm currently typesetting
and found this thread again.

I am just wondering: Reinhold, are you still working on this?

I am aware of the workaround of LSR 473 (and already used it although
it is a "bad trick" and still does not print number 1, thus requiring
another even worse trick).

Cheers,
Xavier
