iperf 2.0.2 compile on FreeBSD 4.10

[Jim Mozley <jim.mozley --at-- exponential-e.com>]

I'm trying to compile iperf 2.0.2 on FreeBSD 4.10 with no success. I've 
tried setting environment variables as per the INSTALL file and also 
tried using configure --disable-threads. In between attempts I have been 
using make distclean.

I see the following errors whatever I seem to do:

make  all-recursive

Can anyone help with this?

Compiler is gcc 2.95.4, the one installed with FreeBSD 4.10.
