Here's the environment data submitted to ./configure for a recent build of 8.1.5:
pgdba@ydb1 $ ./pg_config --configure '--prefix=/where/I/stow/it '--enable-thread-safety' '--enable-debug' '--with-libraries=/opt/freeware/lib' '--with-includes=/opt/freeware/include' 'CC=gcc -maix64' 'LDFLAGS=-Wl,-bmaxdata:0x80000000,-bbigtoc'
Note that you also need to export:
export OBJECT_MODE=64
And you need to make sure that you are using the AIX ld, and not GNU ld...
For version 7.4, it was considerably fiddlier to do a build. For 8.2,
it is neither overly baroque nor overly unpleasant, which I consider a
direct result of the combination of Seneca Cunningham's reports to
-hackers/-ports as well as BuildFarm runs...
