[rfc] [4/7] Modernize AIX target: inf-ptrace build fix

["Ulrich Weigand" <uweigand@de.ibm.com>]

Hello,

this is another small build fix that is a pre-requisite for the
next patch (which adds inf-ptrace.c on AIX).  The problem is that
on AIX, PTRACE_TYPE_ARG3 is a pointer, and trying to cast a
CORE_ADDR directly to it gives a compile warning.

The patch adds an intermediate cast to "long" to fix this problem;
there is precedent for this method in inf_ptrace_xfer_partial.

Tested on powerpc-aix-ibm5.3.0.0.

Bye,
Ulrich


ChangeLog:

	* inf-ptrace.c (inf_ptrace_fetch_register): Add intermediate cast
	to "long" before casting CORE_ADDR to PTRACE_TYPE_ARG3.
	(inf_ptrace_store_register): Likewise.
