42d1d32c3dSAlex Richardson  * In some glibc versions (e.g. 2.28) htole16() expands to a call to an inline
43d1d32c3dSAlex Richardson  * function. Clang will complain that this is not a compile time constant if
44d1d32c3dSAlex Richardson  * it is used as a global struct initializer.
45d1d32c3dSAlex Richardson  * Define them as simple macros instead. This is not quite as good since it
46d1d32c3dSAlex Richardson  * won't catch any type errors when calling the macro (e.g. it now happily
47d1d32c3dSAlex Richardson  * accepts pointers) but for the purpose of bootstrapping some tools this
48d1d32c3dSAlex Richardson  * should be fine.
