I'm seeing large numbers of "cast from pointer to integer of different 
size" warnings on x86 builds, around uses of these macros.  I suspect this 
patch is responsible - if code, even in part of an "if" statement that 
won't be executed, contains a pointer-to-integer cast, you need to cast to 
a pointer of the same size as the integer, and possibly then from there to 
a type of the desired final width.

Please watch out for any warnings added by any patch you submit.  I'd like 
us to end up using -Werror, but until then we need to keep watching for 
new warnings manually, and keep cleaning up existing warnings.
