[Patches] printf("%lx") -> printf("%p") for pointers : win64 cares

The sad truth is hinted at here (among many other places; this is just the
first FAQ reference I hit):

    http://www.eskimo.com/~scs/C-faq/q11.2.html

ISO and ANSI derive a lot of income from selling standards, and ISO in
particular refuses to make any standard available over the web until it's
obsolete.  And there's really no substitute for having the actual standard
in hand.  Expect to fork out a few hundred bucks for a current "big" ISO
standard.

It would actually be more efficient for *me* <wink> -- standards are written
in a strange language that only looks like English until you try to
understand them.  I only know this stuff because I worked on a C compiler in
a previous life.

I'd put it in, if I were Guido.

Another irritating possibility is to write your own function to convert a
void* to a hex string.  Then the #ifdef'ing would be needed only inside
that.

Doubt it, but don't know.  I haven't worked on a C compiler in over 5 years,
and I certainly don't spend my own money on C standards <0.5 wink>.
