Trouble compiling conserver 8.0.6 on OpenBSD 3.4

I'm trying to compile conserver 8.0.6 on OpenBSD 3.4, and the build
fails with the following errors:

access.c: In function `AddrCmp':
access.c:88: warning: passing arg 2 of `inet_aton' from incompatible
pointer type
*** Error code 1

Stop in /home/kurt/conserver-8.0.6/conserver.
*** Error code 1

Stop in /home/kurt/conserver-8.0.6 (line 20 of Makefile).

Additionally, the following warning is output by ./configure:

configure: WARNING: sys/proc.h: present but cannot be compiled
configure: WARNING: sys/proc.h: check for missing prerequisite headers?
configure: WARNING: sys/proc.h: proceeding with the preprocessor's result
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to bug-autoconf@gnu.org. ##
configure: WARNING:     ## ------------------------------------ ##

Any suggestions as to how I can get it to compile?  Incidentally,
7.2.7 compiles and runs fine, but I'd rather run 8.0.6.
