Perl has never #defined a PERL_PATCHLEVEL, so I don't think that could
have ever fully "worked". (See diff of patchlevel.h between 5.005_50
and 5.6.0.)

I think the breakage you're referring to may be due to the fact
that __PATCHLEVEL_H_INCLUDED__ has been #defined by default since
5.005_62 (15 October 1999). Certainly not a "last minute change".
