10 * For native compilation of the sandbox we should still align
11 * the contents of stack buffers to something reasonable. The
12 * GCC macro __BIGGEST_ALIGNMENT__ is defined to be the maximum
13 * required alignment for any basic type. This seems reasonable.
14 * This is however GCC specific so if we don't have that available
15 * assume that 16 is large enough.
