The rune I/O functions are about to become deprecated in favour of the
ones provided by ISO C90 Amd. 1 and C99.
called <machine/_types.h>.
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

IEEE Std 1003.1-2001.
- Replace the K&R with ANSI-C function definitions.
- Bring the manual page up-to-date.

While I was at it, fixed a lot more found by ispell that I
could identify with certainty to be errors. All of these

- Remove redundant "? :" construct.
style(9):
- Place a space after return statements.
- Compare pointers to NULL.
- Do not use ! to compare a character to nul.
- New length modifiers: hh, j, ll, t, z.
Still to do:
- %C, %S, %lc, %ls (wide character support)
- %a/%A (exact hex representation of floating-point numbers)
Removed old compatability equivalents:
- %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
were buggy anyway, since they should have represented %Le & %Lf).
- %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d
In original version grouping was hardcoded. It assumed that thousands
separator should be inserted to separate each 3 numbers. I.e. grouping
string "\003" was assumed for all cases. In correct case (per POSIX)
vfprintf should respect locale defined non-monetary (LC_NUMERIC
category) grouping sequence.
Also simplify thousands_sep handling.
- New length modifiers: hh, j, t, z.
- New flag: '. Note that %'f is not yet implemented.
- Use "inf"/"nan" for efg formats, "INF"/"NAN" for EFG formats.
- Implemented %q in terms of %ll; if "quad_t" is not "long long"
%q will break.
Still to do:
- %C, %S, %lc, %ls (wide character support)
- %'f (thousands in integer portion of %f)
- %a/%A (exact hex representation of floating-point numbers)
