offsetof implementation incompatible with c++

In stddef.h c6000 7.4.1

#define offsetof(_type, _ident) ((size_t)__intaddr__(&(((_type *)0)->_ident)))

doesn't work because size_t needs to be qualified with std::

The simplest fix is

#define offsetof(_type, _ident) ((__SIZE_T_TYPE__)__intaddr__(&(((_type *)0)->_ident)))

This is now SDSCM00045504.

Note that this only fails if you include cstddef; if you instead include stddef.h, it works because size_t is introduced into the global namespace.
