  Is this a thank you for the polite input?

  10 of the 14 errors reported were not machine generated.

  I made no claim for coding standards for machine-generated code.  In
general, enforcing any kind of style on this type of code is silly and
fairly hard.  Correctness is the only real metric, and efficiency is a
consideration.

  Note that the 'unused variable m' error at a minimum results in several
meaningless machine instructions.  Keeping track of when/if it is used is
hard, so I have no problem if you want to ignore it.

  Thanks for all your hard work on Snowball.
