Adrian Aichner: <adrian@xemacs.org>

It's XEmacs, not Xemacs: change all the occurences.

[ETAGS_REGEXPS]: Now is unconditionally defined.
[LONG_OPTIONS]: Changed to NO_LONG_OPTIONS, which is undefined.
(Objc_suffixes): Suggest using --lang=c for full help.
(C_entries): Initialise savetoken to 0 to shut up the compiler.

the regex.h distributed with Cygwin is not compatible with etags, alas!
