3025 This replaces the previous %_ "hack" by the "%p" hacks.
3026 All that is required is that the perl source does not
3027 use "%-p" or "%-<number>p" or "%<number>p" formats.
3028 These formats will still work in perl code.
3029 See comments in sv.c for futher details.
3031 -DvdNUMBER=<number> can be used to redefine VDf
3033 -DvdNUMBER=0 reverts VDf to "vd", as in perl5.8.7,
