bug#57065: 29.0.50; Double evaluation in `c-make-no-parens-syntax-table`

[Stefan Monnier via "Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

Package: Emacs
Version: 29.0.50


The patch below seems to be necessary to avoid a double-evaluation.
This can be seen if you do something like

    (c-lang-defconst c-make-mode-syntax-table my-lang #'my-fun)

or

    (c-lang-defconst c-make-mode-syntax-table my-lang (symbol-value 'my-fun))

or

    (c-lang-defconst c-make-mode-syntax-table my-lang
      (lambda () ..))

where you'll get errors like "void-variable `my-fun`" or "void-function
`closure`.
