Can we use `__builtin_bswap{16,32,64}` in these files now?
GCC 4.3 added `__builtin_bswap32(int32_t x)` and `__builtin_bswap64(int64_t x)`. GCC 4.8 added
`__builtin_bswap16(uint16_t x)` and changed the others to unsigned parameters.
For `_byteswap_ushort()`, if compatibility with GCC 4.7- is desired, we can always use `__builtin_bswap32(_Short) >> 16`.
