I didn't check this. Probably, Makefiles are needed in the
subdirectories that define EXTRA_DIST. I will add them later this
week unless somebody else provides a patch.

Good. I'm committing this to cvs, now.

Hm, we already made sure that the compiler understands expressions like
bind<I_location?I_location+1:0> so I'm completely at sea why this still
fails. Could you try to play around with the bind function a bit?
Comment out the return expression and other stuff and see if it works
then. "line 507" as given by the compiler doesn't help much.

Thanks!
