[phobos] phobos commit, revision 1924

[Sean Kelly]

Oops.  I'll check that out.  Why not use ptrdiff_t though?  It's already defined in object.d for this purpose, and unlike ssize_t it's a standard C typedef.

For example, OSX's /usr/include files definite set it to be a long, not a size_t as set in types.d. It looks like all the aliases need to be double checked.
