o Unify <machine/endian.h>'s across all architectures. o Make bswapXX() functions use a different spelling of u_int16_t and friends to reduce namespace pollution. The bswapXX() functions don't actually exist, but we'll probably import these at some point. Atleast one driver (if_de) depends on bswapXX() for big endian cases. o Deprecate byteorder(3) prototypes from <sys/types.h>, these are now prototyped indirectly in <arpa/inet.h>. o Deprecate in_addr_t and in_port_t typedefs in <sys/types.h>, these are now typedef'd in <arpa/inet.h>. o Change byteorder(3) prototypes to use standards compliant uint32_t (spelled __uint32_t to reduce namespace pollution). o Document new preferred headers and standards compliance.

* The rune type above is declared to be an ``int'' instead of the more natural

|

* chosen over a long is that the is*() and to*() routines take ints (says
|
|
* ANSI C), but they use _BSD_CT_RUNE_T_ instead of int. By changing it
|
|
* here, you lose a bit of ANSI conformance, but your programs will still
|
|
* work.

*
|
|
* NOTE: rune_t is not covered by ANSI nor other standards, and should not
|
|
* be instantiated outside of lib/libc/locale. Use wchar_t. wchar_t and
|
|
* rune_t must be the same type. Also wint_t must be no narrower than
|
|
* wchar_t, and should also be able to hold all members of the largest
|
|
* character set plus one extra value (WEOF). wint_t must be at least 16 bits.
