[texhax] No room for new \count

Can you figure out which line of code is causing the error?  (it
should show up after "l." in the error message).  If you want to see
more details of how TeX got there, you can try setting
\errorcontextlines=100 to get more context.

Without knowing anything else, though, my guess would be that you're
including a bunch of other packages that all have their own counters,
and together you're going over the limit.  \newcount is declared
\outer by default, so there shouldn't be any way of looping over it.

Also, eTeX provides many more count registers, though I don't know the
details of how to use it (or if that's on by default).
