[patch]: Fix windows x64 build

[Kai Tietz <Kai.Tietz@onevision.com>]

Hello,

I noticed that building of w64 was broken by a warning in gdbarch.c by 
casting a pointer to long type.

ChangeLog

2009-02-11  Kai Tietz  <kai,tietz@onevision.com>

        * gdbarch.c (gdbarch_dump): Cast via size_t to long.

Is this patch ok to apply?
