Connecting to old 7.1 Database

Hi All,

I need to connect to a version 7.1 PostgreSQL database. Unfortunately, I
cannot get the 7.1.3 source to compile. configure gives this error:

checking types of arguments for accept()... configure: error: could not
determine argument types

I'm not posting to pgsql-bugs because I think this is to do with me
having a much newer environment (gentoo linux) than was around when
7.1.3 was released.

So, two questions:

- Is there anyway to run a newer version (8.3.5) of psql in some sort of
'backwards compatible' mode?

- Do you have any tips on making 7.1.3 compile on a newer system?

Many thanks
Andy
