AIX vs. PostgreSQL

Version of Postgres: 6.4.2
Operating system: AIX 4.3.2.0
Hardware: PowerPC RS/6000

Compile:
  With gcc, I had to add "-D_LONG_LONG" to COPT.  (I compiled using the
  aix_gcc template, which should probably be updated.)

  The native lex/yacc *both* complained of limits being exceeded.  This
  was fixed by using flex and bison.

  There were problems building the postgres.imp file -- the file was
  created, but a warning was emitted and the make stopped.  Since the
  file was created, subsequent runs would skip that step.  I suspect an
  incompatibility between the AIX mkldexport.sh script and gcc.

  There were many warnings about int8, int16, int32 redefinitions (see
  below).

Install:
  No problems.  Postmaster seems to run all right, and psql connects and
  creates/manipulates the test database as described in the INSTALL
  documentation.  createdb and destroydb both work.

Regression test:
  Could not run at all!
