Yup, you're right.

How about the following, then, at the very beginning of the documentation
for alpha-dec-linux? Upgrading to 2.10 seems to fix all these problems.

Or just add that single sentence and remove all remarks concerning Red Hat
4.2 and 5.0?

  it will silently generate incorrect code.  The version shipped with
  Red Hat 5.0 (2.8.0.1) is not broken, but required an extra -m21164a
  argument on the command-line.  In order to visibly trap 2.7.0.2,
! I now issue DEC's .arch pseudo into the assembly.  Relieving the
  problem of mucking with command-line arguments for 2.8.0.1 is a
  pleasant side effect.</p>
