3007 This replaces the previous %_ "hack" by the "%p" hacks.
3008 All that is required is that the perl source does not
3009 use "%-p" or "%-<number>p" or "%<number>p" formats.
3010 These formats will still work in perl code.
3011 See comments in sv.c for futher details.
3013 -DvdNUMBER=<number> can be used to redefine VDf
3015 -DvdNUMBER=0 reverts VDf to "vd", as in perl5.8.7,
