A couple comments on this patch ...

The immediately previous code would default to CFLAGS="-g" if
--enable-debug is specified and the compiler is not gcc. As it
now stands, we default to CFLAGS="-O -g" instead. I'm not convinced
this is a good idea. On most non-gcc compilers, this combination
gets you "-g" and possibly a ton of warnings.

I think you changed the behavior for the AIX port. Diffing
src/template/aix against the old contents:

diff -c -r1.11 -r1.14
*** pgsql-server/src/template/aix 2002/09/04 22:54:18 1.11
--- pgsql-server/src/template/aix 2003/10/25 15:32:11 1.14

! fi

The "case" is now useless because CFLAGS will always end up with the
later setting. Don't we want something like

if test "$GCC" != yes ; then
case $host_os in
aix3.2.5 | aix4.1*) CFLAGS='-qmaxmem=16384 -qsrcmsg' ;;
*) CFLAGS='-O2 -qmaxmem=16384 -qsrcmsg -qlonglong' ;;
esac
fi
