2003-07-08 Martin Stjernholm <bug-cc-mode@gnu.org>

	* cc-engine.el (c-guess-basic-syntax): Do not do hidden buffer
	changes; there's third party code that calls this function
	directly.

2003-07-07  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* cc-fonts.el (javadoc-font-lock-keywords,
	autodoc-font-lock-keywords): Don't byte compile on font lock
	initialization when running from byte compiled files.

2003-07-06  Alan Mackenzie  <bug-cc-mode@gnu.org>

	* cc-engine.el: Fix AWK mode indentation when previous statement
	ends with auto-increment "++".

2003-07-05  Martin Stjernholm  <bug-cc-mode@gnu.org>

	* cc-langs.el, cc-styles.el (c-style-alist, c-lang-variable-inits,
	c-lang-variable-inits-tail): The values of these are changed, so
	declare them as variables and not constants.
