detect emacs/xemacs in elisp?

[Jason Addison]

I have some elisp that works/doesn't work in emacs/xemacs in my
".emacs" file. I would like to be able to execute or not execute code
depending on which type of emacs I'm running. Another way around this
would be to know how to determine if a function is defined before
calling it. Any idea on how to do this in elisp? Also, how do you
determine the version of emacs that is running in elisp?

Thanks, Jason

(if (featurep 'xemacs)
    (progn
      ;; do Xemacs stuff
      )
  ;; do Emacs stuff
  )

Use `fboundp' to determine if a function is defined.

E.g the function `emacs-version'.

In my mail groups, I have to tried to jump to the last article by
variously pressing 'l' and 'C-u l' but neither of them seem to work on a
reliable basis.  Either the cursor stays where it is (oldest mail) or it
opens the oldest mail.  Using the menu option also does nothing.

What's going on?

Bad!
Please send a bug-report (after checking with whoever made the Emacs.app
package that he followed the normal instructions).
M-x report-emacs-bug is the way to send a bug-report, BTW.

I am using emacs 21.2.1 in a redhat 7.3 distribution.  Can a pixmap be 
set as the background rather then a color?

Thanks,

Tom
