2954 This replaces the previous %_ "hack" by the "%p" hacks.
2955 All that is required is that the perl source does not
2956 use "%-p" or "%-<number>p" or "%<number>p" formats.
2957 These formats will still work in perl code.
2958 See comments in sv.c for futher details.
2960 -DvdNUMBER=<number> can be used to redefine VDf
2962 -DvdNUMBER=0 reverts VDf to "vd", as in perl5.8.7,
2963 which works properly but gives compiler warnings
