Trouble compiling postgres 7.4 on aix 4.3.3 using gcc

Hi, hopefully someone can help with this since postgres is listed as working
with AIX, and some people seem to have got the release candidates working
with AIX.

When I compile postgres using gmake and gcc 2.95.3 I get the error below -
I'm just using a straighforward ./configure, I've tried various switches but
none have made a difference.

It seems like one of the libraries is missing an -lsomething during the
compile, but I've no idea what.

ld: 0711-317 ERROR: Undefined symbol: .PQresultErrorField
ld: 0711-317 ERROR: Undefined symbol: .last_path_separator
ld: 0711-317 ERROR: Undefined symbol: .PQsetNoticeReceiver
ld: 0711-317 ERROR: Undefined symbol: .PQfreemem
collect2: ld returned 8 exit status
gmake[4]: *** [libecpg.so] Error 1

Thanks for any help, I do know a bit about C, gcc, and AIX, but not enough
to figure out this issue...
