You're missing the version number, as you mentioned, and the file
"functions.h" which tells the compiler a lot of things it needs to be
happy. This works:

#include<exec/types.h>
#include<intuition/intuition.h>
#include<functions.h>           /* Manx smiles on this file :) */

struct IntuitionBase *IntuitionBase ;

void main(void)
{
	if(IntuitionBase = OpenLibrary("intuition.library", 0L ))
	{
		printf("success\n") ;
		CloseLibrary( IntuitionBase ) ;
	}
	else
	{
		printf("failure\n") ;
	}
}
