PS: For this patch, I needed to know which compiler versions support
__builtin_offsetof. This test program
=================================================
typedef struct { char a; double b; int c; } foo;
int xxx = __builtin_offsetof (foo, c);
#include <stddef.h>
int yyy = offsetof (foo, c);
=================================================
compiled with "$CC -S", showed that
- GCC ≥ 4.0 does,
- at least clang ≥ 2.8 supports it as well.
