Re: 64 bit PostgreSQL 8.3.6 build on AIX 5300-09-02-0849 with IBM XL C/C++ 10.1.0.1 - initdb fails (could not dump unrecognized node type: 650)

The system and compiler are patched with the latest fix packs from IBM, and
the compiler version is the latest available.

The compiler is functional (eg: I was able to compile successfuly 64 bit
versions other software such as Apache 2.2.11, emacs 22.3, vim 7.2,
openssl-0.9.8j and so on, all with similar flags).

So if this is a compiler bug, it certainly isn't an obvious one. I'll dig
deeper to see how I can convince configure to use -qnooptimize.

The first build was using default options for xlC_r (the default for all IBM
compilers is -qnooptimize). ./configure seems to override this:

When I've used the build farm scripts, configure gives xlC_r these flags:

configure:7117: xlC_r -q64 -o conftest -O2 -qmaxmem=16384 -qsrcmsg
-qlonglong -g -I/opt/freeware/include/libxml2 -L/opt/freeware/lib
conftest.c -lm >&5
1506-396 (W) Option -qlonglong is incompatible with option -qlanglvl=extc99
and is ignored.
ld: 0711-317 ERROR: Undefined symbol: .setproctitle
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more
information.
configure:7123: $? = 8

I'll try a 32 bit build too.
