It was confusing for me as well.  I'll track it down if the problem
persists after gettext 0.10.3 is integrated.

"etc."?  :-)

You're right, the muscles themselves are simple, but the overall
process isn't something I fully understand.  For example, the current
CVS bison leaves behind droppings like /tmp/bsnW1ayDm if it fails on
Solaris, and I don't know why.  I can investigate later (I'm a bit
pressed for time now).

I suspect that if I'm running into these problems that users will too,
and it may be necessary to have a brief mention in the manual of the
overall process, including what sort of phases and/or temporary files
that Bison uses.  This could serve as a warmup for a larger part of
the manual that is less urgent, that would be mostly for maintainers
and tell them how to add new skeletons.  (Easy for me to say, huh? :-)
