Thanks to your effort, compile and install finish without errors on both
emacs 21 and xemacs.  Unfortunately, there seems to remain
incompatibility during the run-time.  TAB sometimes raises error.  Here
is the detail.

(1) On emacs 21.4 or xemacs 21.4.22, put the point on the line with a
sole ampersand in the following code in the buffer of latex mode.
\begin{tabular}{lcr}
  a & b & c \\
  &
\end{tabular}
(2) Type TAB.  Then it signals an error 'Wrong type argument:
number-or-marker-p, "0 occurrences"'. (Xemacs emits a bit different
message, "number-char-or-marker-p" instead of "number-or-marker-p",
which I assume essentially the same.)

The reason of the error seems to be the return value of the function
how-many.  Both emacs 21 and xemacs returns the string that reports the
number of the occurrence, not the number itself.

In addition, xemacs does not seem to accept 'min-colors' in the defface.
Xemacs reports the following warnings in the *Warnings* buffer when
opening an ordinary latex file.

(1) (warning/warning) Unknown req `min-colors' with options `(88)'

(2) (warning/warning) Unknown req `min-colors' with options `(88)'

(3) (warning/warning) Unknown req `min-colors' with options `(16)'

(4) (warning/warning) Unknown req `min-colors' with options `(16)'

(5) (warning/warning) Unknown req `min-colors' with options `(8)'

(6) (warning/warning) Unknown req `min-colors' with options `(16)'

P.S. I just noticed that xemacs raises another error "Wrong number of
arguments: #<subr local-variable-p>, 1" every time I open a tex file,
once after AUCTeX is activated.
