/* The preceding attribute is necessary on targets with
BIGGEST_ALIGNMENT <= 32 to trigger the warning, as otherwise a 32 bit
offset is split into DECL_FIELD_OFFSET 4 and DECL_FIELD_BIT_OFFSET 0,
BIGGEST_ALIGNMENT <= POINTER_SIZE to trigger the warning, as
otherwise the offset of 'a' (i.e. POINTER_SIZE) is split into a
non-zero DECL_FIELD_OFFSET and a zero DECL_FIELD_BIT_OFFSET,
and then there is no discrepancy between DECL_FIELD_OFFSET and
byte_position to warn about.
On the other hand 64-bit targets for example, generally need a larger
requested alignment to get the intended warning. */
