snort 2.0.1 compilation errors on openbsd 2.9

[Bill Schwanitz <bilsch () secureinteriors com>]

Has anyone else had difficulties compiling snort 2.0.1 on openbsd 2.9 
WITH flexresp?

configure line: ./configure --enable-flexresp

I get the following errors from the compiler:

I have tried compiling from the same tarball on OpenBSD 3.1 with 
success, it just does not want to compile on 2.9.

Any suggestions?
