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!
