Perhaps you can explain it to us?  :-) More seriously: does an
explanation belong in the Autoconf manual somewhere?  I don't often
use XEmacs, so I hope it works with GNU Emacs.

I'm afraid you'll have to spell out the character ranges, e.g.:

ETAGS_SH = --lang=none 
--regex='/\([abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_][abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ_0123456789]*\)=/\1/'
 \

as 'a-z' isn't portable outside the C locale and (as far as I can see)
there's no guarantee that the regex is interpreted in the C locale.

Other than that, the change looks good if it works for you.
