/* Converts an internet address from internal format to a printable,

AF is an internet address family, such as AF_INET or AF_INET6.
SRC points to a 'struct in_addr' (for AF_INET) or 'struct in6_addr'
(for AF_INET6).
DST points to a buffer having room for CNT bytes.
The printable representation of the address (in numeric form, not
surrounded by [...], no reverse DNS is done) is placed in DST, and
DST is returned. If an error occurs, the return value is NULL and
errno is set. If CNT bytes are not sufficient to hold the result,
the return value is NULL and errno is set to ENOSPC. A good value
for CNT is 46.

dnl that contains a configuration script generated by Autoconf, under
dnl the same distribution terms as the rest of that program.
dnl This file defines some "once only" variants of standard autoconf macros.

dnl The advantage is that the check for each of the headers/functions/decls
dnl will be put only once into the 'configure' file. It keeps the size of
dnl the 'configure' file down, and avoids redundant output when 'configure'
dnl is run.
dnl The drawback is that the checks cannot be conditionalized. If you write
dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
dnl empty, and the check will be inserted before the body of the AC_DEFUNed
dnl function.
dnl This is like onceonly.m4, except that it uses diversions to named sections
dnl DEFAULTS and INIT_PREPARE in order to check all requested headers at once,
dnl thus reducing the size of 'configure'. Works with autoconf-2.57. The

reported by James Lemley on 2005-10-05; see
http://lists.gnu.org/archive/html/bug-coreutils/2005-10/msg00086.html
This test is not quite right, since xlc is allowed to
reject this program, as the initializer for xlcbug is
not one of the forms that C requires support for.
However, doing the test right would require a run-time
test, and that would make cross-compilation harder.
Let us hope that IBM fixes the xlc bug, and also adds
support for this kind of constant expression. In the
meantime, this test will reject xlc, which is OK, since
our stdbool.h substitute should suffice. We also test
this with GCC, where it should work, to detect more
quickly whether someone messes up the test in the
future. */

Programs that use <stdbool.h> should be aware of some limitations
and standards compliance issues.
Standards compliance:
- <stdbool.h> must be #included before 'bool', 'false', 'true'
can be used.
- You cannot assume that sizeof (bool) == 1.
- Programs should not undefine the macros bool, true, and false,
as C99 lists that as an "obsolescent feature".
Limitations of this substitute, when used in a C89 environment:
- <stdbool.h> must be #included before the '_Bool' type can be used.
- You cannot assume that _Bool is a typedef; it might be a macro.
- Bit-fields of type 'bool' are not supported. Portable code
should use 'unsigned int foo : 1;' rather than 'bool foo : 1;'.
- In C99, casts and automatic conversions to '_Bool' or 'bool' are
performed in such a way that every nonzero value gets converted
to 'true', and zero gets converted to 'false'. This doesn't work
with this substitute. With this substitute, only the values 0 and 1
give the expected result when converted to _Bool' or 'bool'.
Also, it is suggested that programs use 'bool' rather than '_Bool';
this isn't required, but 'bool' is more common. */

so that gdb prints values of type 'bool' symbolically. But if we do
this, values of type '_Bool' may promote to 'int' or 'unsigned int'
(see ISO C 99 6.7.2.2.(4)); however, '_Bool' must promote to 'int'
(see ISO C 99 6.3.1.1.(2)). So we add a negative value to the
enum; this ensures that '_Bool' promotes to 'int'. */
