    640919 Fix build for autoconf < 2.64
    
    	* configure.ac: Require autoconf 2.63 instead of 2.64 because EL6
    	has 2.63. More AC_PREREQ after AC_INIT, for consistency. That
    	macro is the only one that can be invoked before AC_INIT, but
    	let's move it after AC_INIT like all other macros.
    	* src/workbench/nmv-workbench.cc: PACKAGE_URL is only defined by
    	AC_INIT on autoconf >= 2.64. Let's define it ourselves for
    	earlier versions.
