44404f3945 Adjust configure to use "+Olibmerrno" with HP-UX C compiler, if possible.
This is reported to be necessary on some versions of that OS.  In service
of this, cause PGAC_PROG_CC_CFLAGS_OPT to reject switches that result in
compiler warnings, since on yet other versions of that OS, the switch does
nothing except provoke a warning.

Report and patch by Ibrar Ahmed, further tweaking by me.

29259531c7 Replace self written 'long long int' configure test by standard 'AC_TYPE_LONG_LONG_INT' macro call. 2010-05-25 17:28:20 +00:00

555a02f910 Added a configure test for "long long" datatypes. So far this is only used in ecpg and replaces the old test that was kind of hackish. 2010-05-25 14:32:55 +00:00

e08ab7c312 Support inlining various small performance-critical functions on non-GCC
compilers, by applying a configure check to see if the compiler will accept
an unreferenced "static inline foo ..." function without warnings.  It is
believed that such warnings are the only reason not to declare inlined
functions in headers, if the compiler understands "inline" at all.

623f8a0969 Modify the recently-added probe for -Wl,--as-needed some more, because RHEL-4
vintage Linux is even more broken than we realized: a link to libreadline
will succeed, and fail only at runtime.  It seems that an AC_TRY_RUN test
is the only reliable way to check whether this is really safe.  Per report
from Tatsuo.

1ac1bea076 Adjust -Wl,--asneeded test to avoid using the switch if it breaks
libreadline.  What we will do for compatibility :-(

2dad10f467 Make another try at using -Wl,--as-needed to suppress linking of unnecessary
shared libraries.  We've tried this before and had problems with libreadline
not linking properly on some platforms, but that seems to be a libreadline
bug that may have been fixed by now.  In any case, it's early enough in the
8.4 devel cycle that we can afford to have some transient breakage while
we work out any portability problems.

On Darwin, we try -Wl,-dead_strip_dylibs, which seems to be the equivalent
incantation there.

7861d72ea2 Modify the float4 datatype to be pass-by-val. Along the way, remove the last
uses of the long-deprecated float32 in contrib/seg; the definitions themselves
are still there, but no longer used.  fmgr/README updated to match.

I added a CREATE FUNCTION to account for existing seg_center() code in seg.c
too, and some tests for it and the neighbor functions.  At the same time,
remove checks for NULL which are not needed (because the functions are declared
STRICT).

I had to do some adjustments to contrib's btree_gist too.  The choices for
representation there are not ideal for changing the underlying types :-(

Original patch by Zoltan Boszormenyi, with some adjustments by me.

b120382353 Upgrade to Autoconf 2.61:
- Change configure.in to use Autoconf 2.61 and update generated files.
- Update build system and documentation to support now directory variables
  offered by Autoconf 2.61.
- Replace usages of PGAC_CHECK_ALIGNOF by AC_CHECK_ALIGNOF, now available
  in Autoconf 2.61.
- Drop our patched version of AC_C_INLINE, as Autoconf now has the change.

857e210ea9 When using GCC, change the default CFLAGS to:
-O2 -Wall -Wmissing-prototypes -Wpointer-arith

Check whether the version of GCC we are using supports any of:

  -Wdeclaration-after-statement
  -Wendif-labels
  -Wold-style-definition

And add the supported flags to CFLAGS.

801427abc2 Unset CFLAGS before reading template. This should be more robust.
When --enable-debug is used, then the default CFLAGS for non-GCC is just
-g without -O.

Backpatch enhancement of Autoconf inline test that detects problems with
the HP C compiler.

f690920a75 Infrastructure for upgraded error reporting mechanism. elog.c is
rewritten and the protocol is changed, but most elog calls are still
elog calls.  Also, we need to contemplate mechanisms for controlling
all this functionality --- eg, how much stuff should appear in the
postmaster log?  And what API should libpq expose for it?

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.

7c1ff35410 Upgrade to Autoconf version 2.53. Replaced many custom macro
calls with new or now-built-in versions.  Make sure that all
calls to AC_DEFINE have a third argument, for possible use of
autoheader in the future.

15abc7788e More correct way to check for existence of types, which allows to specify
which include files to consider.  Should fix BeOS problems with int8 types.

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. :(
