Severity: wishlist

The attached patch removes the XEmacs compatibility code from sql.el.

The Emacs FAQ currently has this to say:

    4.11 What was XEmacs?
    =====================

    XEmacs was a branch version of Emacs that is no longer actively
    developed.  Originally known as “Lucid Emacs”, XEmacs was forked from a
    prerelease version of Emacs 19.  XEmacs last released a new version on
    January 30, 2009, which lacks many important features that exist in
    Emacs.  Since its development has stopped, we do not expect to see any
    new releases.

       In the past, it was not uncommon for Emacs packages to include code
    for compatibility with XEmacs.  Nowadays, most built-in and third party
    packages have either stopped supporting XEmacs or were developed
    exclusively for Emacs.

IOW, this support is probably not relevant to maintain these days.

Any objections to the attached patch?
