Looks like there was an error in 'flymake.el' -- looks like they had
typed an extra '-alist'? See code and comment I put in my local copy:

   ;; compilation-error-regexp-alist)
   ;; Was compilation-error-regexp-alist-alist below.  That seems to
be an error.             -- cbalz 2008-01-23
   (flymake-reformat-err-line-patterns-from-compile-el compilation-
error-regexp-alist))  ;;   -- cbalz 2008-01-23

Using 'M-x describe-variable', I get the correct definition for
'compilation-error-regexp-alist'.

Yet now that 'flymake-js.el' runs without error and starts up (showing
on the modeline), I get this problem, which totally removes Emacs'
ability to save files!  Any idea here?
