I doubt it's possible. All the traditional approaches to endianness tests
are "initialize variable, peek into variable". But variable
initializations don't exist at compile time.

Personally, I wouldn't worry about it. The current tests works if you're
not cross-compiling, and if you are then you are smart enough to make the
test at run-time, use the <endian.h> macros wisely, use ntohl(), or avoid
any dependency on endianness.
