This commit was manufactured to restore the state of the 5.3-RELEASE image.

MFC: don't forget to va_end() after va_copy().

The third operand of the conditional operator should have type void too.

Rename cantwrite() to prepwrite(). The latter is less confusing,

2004-06-08T05:45:32+00:00

since the macro isn't really a predicate, and it has side-effects.

- To make it easier to compile printf() and scanf() without

  floating-point support, remove default definition of FLOATING_POINT
  from the source, and change the compile-time option to
  NO_FLOATING_POINT.
- Remove the HEXFLOAT option.  It saves an insignificant amount of
  space (<0.1% of the size of libc on i386) and complicates vfprintf()
  and checkfmt().

Use the correct size to allocate, copy and clear argument type tables

after their change from an array of char to an array of enum.
This fixes problems that occurred when using positional arguments in
format strings, particularly with more than STATIC_ARG_TBL_SIZE (8)
of them.

Prepare to handle trivial state-dependent encodings. Full support for

2004-04-07T09:55:05+00:00

state-dependent encodings with locking shifts will come later if there
is demand for it.

Implement hdtoa() and hldtoa() and enable printf() support for %a

2004-01-18T10:32:49+00:00

and %A, which print floating-point numbers in hexadecimal.

Fix some bugs affecting the %a and %A format specifiers. Since

2004-01-18T08:28:32+00:00

these are not fully implemented and ifdef'd out, the bugs have
never manifested themselves.  Specifically:

	- Fix a memory leak in the case where %a follows another
	  floating-point format.
	- Make the %a/%A code behave like %e/%E with respect to
	  precision.
	- It is no longer valid to assume that '-' and '0x' are
	  mutually exclusive.
	- Address other minor issues.

Pass NULL instead of a pointer to a zeroed mbstate_t object.
