Just to clarify, the problem with universal binary support is with the
header file and specifically with configure generating a header file
specifically for one platform.

Since building universal binaries effectively compile the code for each
platform, you don't want a header file that is specific to a platform.

This is a similar, but different, problem to the cross-compiling problem.
You can't run target built binaries in a cross-compiling environment.

The union method of endian conversion (which might get optimized
correctly) or my version (which also might get optimized correctly)
would work fine for both universal binaries and cross-compiling.
