3000 This replaces the previous %_ "hack" by the "%p" hacks.
0dbb1585 3001 All that is required is that the perl source does not

3002 use "%-p" or "%-<number>p" or "%<number>p" formats.
3003 These formats will still work in perl code.
3004 See comments in sv.c for futher details.
3005
3006 -DvdNUMBER=<number> can be used to redefine VDf
3007
3008 -DvdNUMBER=0 reverts VDf to "vd", as in perl5.8.7,
3009 which works properly but gives compiler warnings
