gcc is not an ANSI C.  Try gcc -pedantic.

See info of gcc and follow
	* C Extensions::
	    * Function Prototypes::
and you will find the description about the behaviour.

Such an "extension" might be useful for building applications,
but the library and kernel (for LKM) should not depend on this,
in my opinion.
