// We use the compiler builtins __SIZE__TYPE__ and __PTRDIFF_TYPE__ instead of
// std::size_t and std::ptrdiff_t respectively. This makes us independant of
// the conformance level of <cstddef> and whether -fhonor-std was supplied.
// <cstddef> is not currently available during compiler building anyway.
// including <stddef.h> would be wrong, as that would rudely place size_t in
// the global namespace.
#include <typeinfo>
// This should really be cstddef, but that currently is not available when
// building the runtime.
