bug#1729: 23.0.60; (require 'cc-langs) causes an error

bug#1729: 23.0.60; (require 'cc-langs) causes an error

[Ian Eure]

If you eval the following code:

(require 'cc-mode)
(require 'cc-langs)

The following error is triggered:

`c-lang-defconst' must be used in a file

This seems to be a bug. It appears that either (c-get-current-file) is  
buggy, or ‘load-in-progress isn’t being set correctly when (require)  
is called.

This works in the current CVS trunk, perhaps due to the
load-in-progress fixes from July.
