Hi Mark,
Removed the unnecessary casts from pid in rs6000-nat.c as well.
If it is Okay to commit, Ulrich, kindly find the Changelog and
attached patch below.

This patch changes configure.ac so configure and config.in should
be regenerated.

Changelog :-

* gdb_ptrace.h: Use ptrace64 instead of ptrace if HAVE_PTRACE64 is defined.
* rs6000-nat.c: Check for __ld_info64_ if compiling 64 BIT gdb.
(rs6000_ptrace32): Call ptrace64 instead of ptrace if present.
(rs6000_ptrace64): Call ptace64 instead of ptracex if present.
* configure.ac: Check for ptrace64.
* configure, config.in: Regenerate.
