They aren't supported in the sense of being valid floating-literals. It's simply the case that if the 'p' or 'P' is followed by a digit, rather than by '+' or '-', then it forms part of the pp-number whatever standard version is in use (and so none of the lexical complications arise that occur in the p+ / p- / P+ / P- cases, so handling p<digit> as an extension is easy).
