o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED
typedef __foo_t foo_t;
#define _FOO_T_DECLARED
#endif

<stdint.h>. Previously, parts were defined in <machine/ansi.h> and
<machine/limits.h>. This resulted in two problems:
(1) Defining macros in <machine/ansi.h> gets in the way of that
header only defining types.
(2) Defining C99 limits in <machine/limits.h> adds pollution to
<limits.h>.
hardly MD, since all our platforms share the same macro. It's not
really compiler dependent either, but this helps in reducing
<machine/ansi.h> to only type definitions.
patch from a year ago: give file flags their own type. This does not
(yet) change the type used by system calls or library functions.
The underlying type was chosen to match what is returned by stat().
o Hide nonstandard functions and types in <netinet/in.h> when
_POSIX_SOURCE is defined.
o Add some missing types (required by POSIX.1-200x) to <netinet/in.h>.
o Restore vendor ID from Rev 1.1 in <netinet/in.h> and make use of new
__FBSDID() macro.
o Fix some miscellaneous issues in <arpa/inet.h>.
o Correct final argument for the inet_ntop() function (POSIX.1-200x).
o Get rid of the namespace pollution from <sys/types.h> in
<arpa/inet.h>.

o Make <stdint.h> a symbolic link to <sys/stdint.h>.
o Move most of <sys/inttypes.h> into <sys/stdint.h>, as per C99.
o Remove <sys/inttypes.h>.
o Adjust includes in sys/types.h and boot/efi/include/ia64/efibind.h
to reflect new location of integer types in <sys/stdint.h>.
o Remove previously symbolicly linked <inttypes.h>, instead create a
new file.
o Add MD headers <machine/_inttypes.h> from NetBSD.
o Include <sys/stdint.h> in <inttypes.h>, as required by C99; and
include <machine/_inttypes.h> in <inttypes.h>, to fill in the

friends to reduce namespace pollution. The bswapXX() functions
don't actually exist, but we'll probably import these at some

o Deprecate in_addr_t and in_port_t typedefs in <sys/types.h>, these

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.

- created internal names for fixed-size integral types, like __int32_t. They
will be used to make several headers self-sufficient.
- <stdlib.h> don't include <machine/types.h> anymore.
- created <sys/inttypes.h>, which can be used as <inttypes.h>.
- declaration of uoff_t and ufs_daddr_t moved to <sys/types.h>.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
Fixed longstanding namespace convolution involving rune_t vs wchar_t...
This change breaks similar (but more convoluted) convolutions in the
stddef.h in gcc distributions. Ports of gcc should avoid using the
gcc headers.
of the typedefs off_t and pid_t when use of the latter would cause
namespace pollution. These macros are used like _BSD_VA_LIST_ and
aren't #undef'ed when the corresponding typedef is declared.
off_t is very machine-dependent and should never have been decided
in <sys/types.h> (its declaration is compiler-dependent). pid_t
isn't very machine-dependent, but this might change. `long' is
a wasteful type for it if longs are longer than ints.
Move the definition of _BSD_VA_LIST_ away from the comment that
suggests that it is #undefed when va_list is declared.

I have left the old _ctype_ array in place, and moved the ctype.h
header to octype.h, so that existing shared binaries will still be
able to find and use it as they require.
See /usr/src/share/locale for information on how to create new locale
data files (eventually this procedure will be improved). I'd like to
have a family of locale files for various countries, languages, and
character sets, so please contribute some.
This code was originally written by Paul Borman and contributed to
4.4; I did the integration, and have somewhat tested it. crt0.c
probably ought to call setlocale() if it doesn't already, but I'd like
for people to create some locale files and try things manually first
before I make every program do this.
