2976 This replaces the previous %_ "hack" by the "%p" hacks.
2977 All that is required is that the perl source does not
2978 use "%-p" or "%-<number>p" or "%<number>p" formats.
2979 These formats will still work in perl code.
2980 See comments in sv.c for futher details.
2982 -DvdNUMBER=<number> can be used to redefine VDf
2984 -DvdNUMBER=0 reverts VDf to "vd", as in perl5.8.7,
