The GNU standards specify what --version output should look like.
This output does not match the GNU standard.  That should be fixed in
the binutils, or in S.U.S.E.'s build.

Specifically:

    @cindex canonical name of a program
    @cindex program's canonical name
    The first line is meant to be easy for a program to parse; the version
    number proper starts after the last space.  In addition, it contains
    the canonical name for this program, in this format:

    @example
    GNU Emacs 19.30
    @end example

The 20070219 above should be attached to the 2.17.50.20070219.  Or
simply omitted--I don't know why the date is doubled.
