This option is not enabled by default because many existing tests
use integer assertions to check the pointers:
TEST_ASSERT_EQUAL(NULL, pointer)
This causes a "cast from pointer to integer of different size"
(-Wpointer-to-int-cast) warning to be generated, as Unity converts
every argument to UNITY_UINT first, and with 64-bit support enabled,
UNITY_UINT becomes a 64-bit unsigned type.
