AIX faq said that xlC compiler don't work with libpq++ but with g++ it
may works :

Humm, I have no xlC compiler installed.Here are the compilation lines :

All work until it want to link with libraries, it seems to want the libc
(-lc) and I don't
have it installed. Is it normal or this realease is not portable with AIX
4.3.3 ?
