Unable to get Postgres to compile on my system

I'm running RedHat Linux 5.1 (kernel 2.0.34) on a 686 machine.
Attached is the generated make.log that fails when compiling
hba.c.

I'm attempting to compile v6.5 and this is a new installation,
I'm not upgrading from a previous version of postgres.
The version of flex on my system is 2.5.4.

Any help would be much appreciated!

Tim
