BYTE_ORDER and BIG_ENDIAN are in the user's namespace.  You have to use 
implementation-namespace macros in such conditionals in installed headers.

No.  This *must* be unnamed in the installed header, so that initializers 
in user code { seconds, nanoseconds } continue to work as expected (even 
if not formally required to work by the standards, I think it's clear we 
should keep code with such initializers working).
