adding javascript enable to netsurf

[kokamoto@hera.eonet.ne.jp]

I'm still struggling this.
Error message says:
javascript_init: redifinition: javascript_init
(4481) TEXT javascript_init t0(SB). R0, $16

javascript_init is declared only once in
./netsurf/content/handlers/javascript/content.h:
nserror javascript_init(void);

However, I cannot find the body of that function anywhere...

The javascript_init is called from ./netsurf/content/handlers/javascript/duktape/dukky.c like:

/* exported interface documented in js.h */
void js_initialise(void)
{
	/** TODO: Forces JS on for our testing, needs changing before a release
	 * lest we incur the wrath of others.
	 */
	/* Disabled force-on for forthcoming release */
	/* nsoption_set_bool(enable_javascript, true);
	 */
	javascript_init();  <====
}

Please let me know the meaning of that comment, I'm not native English user,
then, it is difficult to understand why then javascript_init() is used here...
