8883bae33b Remove configure test for nonstandard variants of getpwuid_r().
We had code that supposed that some platforms might offer a nonstandard
version of getpwuid_r() with only four arguments.  However, the 5-argument
definition has been standardized at least since the Single Unix Spec v2,
which is our normal reference for what's portable across all Unix-oid
platforms.  (What's more, this wasn't the only pre-standardization version
of getpwuid_r(); my old HPUX 10.20 box has still another signature.)
So let's just get rid of the now-useless configure step.

7e3f728353 Fix configure check for %z printf support after INT64_MODIFIER changes.
The PGAC_FUNC_SNPRINTF_SIZE_T_SUPPORT test was broken by
ce486056ec. Among others it made the UINT64_FORMAT macro to be
defined in c.h, instead of directly being defined by configure.

This lead to the replacement printf being used on all platforms for a
while. Which seems to work, because this was only used due to
different profiles ;)

Fix by relying on INT64_MODIFIER instead.

ce486056ec Add #define INT64_MODIFIER for the printf length modifier for 64-bit ints.
We have had INT64_FORMAT and UINT64_FORMAT for a long time, but that's not
good enough if you want something more exotic, like "%20lld".

Abhijit Menon-Sen, per Andres Freund's suggestion.

ac4ef637ad Allow use of "z" flag in our printf calls, and use it where appropriate.
Since C99, it's been standard for printf and friends to accept a "z" size
modifier, meaning "whatever size size_t has".  Up to now we've generally
dealt with printing size_t values by explicitly casting them to unsigned
long and using the "l" modifier; but this is really the wrong thing on
platforms where pointers are wider than longs (such as Win64).  So let's
start using "z" instead.  To ensure we can do that on all platforms, teach
src/port/snprintf.c to understand "z", and add a configure test to force
use of that implementation when the platform's version doesn't handle "z".

Having done that, modify a bunch of places that were using the
unsigned-long hack to use "z" instead.  This patch doesn't pretend to have
gotten everyplace that could benefit, but it catches many of them.  I made
an effort in particular to ensure that all uses of the same error message
text were updated together, so as not to increase the number of
translatable strings.

It's possible that this change will result in format-string warnings from
pre-C99 compilers.  We might have to reconsider if there are any popular
compilers that will warn about this; but let's start by seeing what the
buildfarm thinks.

5242fefb47 Be consistent about #define'ing configure symbols as "1" not empty.
This is just neatnik-ism, since all the tests in the code are #ifdefs,
but we shouldn't specify symbols as "Define to 1 ..." and then not
actually define them that way.

f667747b6d Put back AC_REQUIRE([AC_STRUCT_TM]).
The BSD-ish members of the buildfarm all seem to think removing this
was a bad idea.  It looks to me like it resulted in omitting the system
header inclusion necessary to detect the fields of struct tm correctly.

7cc514ac65 Upgrade to Autoconf 2.63
This upgrades the configure infrastructure to the latest Autoconf version.
Some notable news are:
 - The workaround for the broken fseeko() test is gone.
 - Checking for unknown options is now provided by Autoconf itself.
 - Fixes for Mac OS X

b4feafb6ff Add support to port/snprintf.c for position parameter specification:
+ # Determine if printf supports %1$ argument selection, e.g. %5$ selects
+ # the fifth argument after the printf print string.
+ # This is not in the C99 standard, but in the Single Unix Specification (SUS).
+ # It is used in our langauge translation strings.

df63503dc2 Have a go at fixing various outstanding portability issues in code that
was modified for IPv6.  Use a robust definition of struct sockaddr_storage,
do a proper configure test to see if ss_len exists, don't assume that
getnameinfo() will handle AF_UNIX sockets, don't trust getaddrinfo to
return the protocol we ask for, etc.  This incorporates several outstanding
patches from Kurt Roeckx, but I'm to blame for anything that doesn't
work ...

955a1f81a7 Factor out the code that detects the long long int snprintf format into a
separate macro.  Also add support for %I64d which is the way on Windows.

The code that checks for the 64-bit int type now gives more reasonable
results when cross-compiling: In that case we just take the compiler's
information and trust that the arithmetic works.  Disabling int64 is too
pessimistic.

e9c936ff38 Remove rangechecks on errno; just call strerror unconditionally. This
eliminates a raft of portability issues, including whether sys_nerr
exists, whether the platform has any valid negative errnos, etc.  The
downside is minimal: errno shouldn't ever contain an invalid value anyway,
and if it does, reasonably modern versions of strerror will not choke.
This rangecheck idea seemed good at the time, but it's clearly a net loss,
and I apologize to all concerned for having ever put it in.

Unix 9x "standard" do not declare str[n]casemp() in string.h, and C99
compilers will not like that.

06cd0f1a32 Substituted new configure test for types of accept()
Interfaced a lot of the custom tests to the config.cache, in the process
made them separate macros and grouped them out into files. Made naming
adjustments.

Removed a couple of useless/unused configure tests.

Disabled C++ by default. C++ is no more special than Perl, Python, and Tcl.
And it breaks equally often. :(
