Gnus and No Gnus

[Katsumi Yamaoka]

Hi,

Today I tried synch'ing the Gnus trunk with the Emacs trunk and
found a problem concerning `float-time'.

In time-date.el, `define-obsolete-function-alias' is not available
in Emacs 21 that Gnus still supports.  It causes an error when
loading gnus-load.el.

In ecomplete.el, gnus-util.el and time-date.el, (featurep 'xemacs)
is used for checking if `float-time' is available like this:

  (if (featurep 'xemacs)
      (time-to-seconds time)
    (float-time time))

However, XEmacs may implement `float-time' in the future.

Therefore I made changes in those files as attached below.  WDYT?
The whole patch that synch the Gnus trunk with the Emacs trunk is:

ftp://ftp.jpl.org/pub/tmp/Gnus-Emacs-20090907.diff.gz
of http://www.jpl.org/ftp/pub/tmp/Gnus-Emacs-20090907.diff.gz
