In 5.9.3, Newx() and friends replace the older New() API, and drops
the first parameter, I<x>, a debug aid which allowed callers to identify
themselves. This aid has been superseded by a new build option,
-PERL_MEM_LOG (see L<perlhack/PERL_MEM_LOG>). The older API is still
+PERL_MEM_LOG (see L<perlhacktips/PERL_MEM_LOG>). The older API is still
there for use in XS modules supporting older perls.
