Backed out changeset 16c9098dd3d2. See http://mid.gmane.org/8763jbsyr7.fsf@xemacs.org for details from Stephen as to why. Basically, there was a bug in his version of Xt that broke the initialisation of the describe-char-unicodedata-file variable; he has found it, and fixed it locally, so this should not longer be an issue.

while (<STDIN>) {
  if (/^\$Revision:\s*([0-9\.]*)/) {
    print "char *version = \"$1\";\n";
    print "static char *id = \"\\n%%% setup-version $1\\n\";\n";
  }
}
