This doesn't work as expected, at least for Emacs 21.  The form

(let ((foo (make-char-table 'syntax-table nil)))
  (char-to-string (with-syntax-table foo (char-syntax ?\())))

returns "(", which indicates that the standard syntax table is used for
an entry which has nil for its value in the current syntax table.

Instead, something like

(setq TeX-search-syntax-table (make-char-table 'syntax-table
      (string-to-syntax " ")))

or

(setq TeX-search-syntax-table (make-char-table 'syntax-table nil))
(set-char-table-parent TeX-search-syntax-table (make-char-table
  'syntax-table nil))

seems to serve the purpose.  See the following examples.

(let ((foo (make-char-table 'syntax-table (string-to-syntax " "))))
  (char-to-string (with-syntax-table foo (char-syntax ?\())))
  => " "

(let ((foo (make-char-table 'syntax-table nil)))
  (set-char-table-parent foo (make-char-table 'syntax-table nil))
  (char-to-string (with-syntax-table foo (char-syntax ?\())))
  => " "
