Summary: configure finds sysctl.h but it does not compile on
                    OpenBSD 4.1
           Product: Wine
           Version: 0.9.37.
          Platform: Other
        OS/Version: OpenBSD
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: wine-ports
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

configure: WARNING: sys/sysctl.h: present but cannot be compiled
configure: WARNING: sys/sysctl.h:     check for missing prerequisite headers?
configure: WARNING: sys/sysctl.h: see the Autoconf documentation
configure: WARNING: sys/sysctl.h:     section "Present But Cannot Be Compiled"
configure: WARNING: sys/sysctl.h: proceeding with the preprocessor's result
configure: WARNING: sys/sysctl.h: in the future, the compiler will take precedence
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to [e-mail] ##

I didn't manage to get the header dependencies right, so I leave
this to those who are used to working with configure scripts.

I got around the problem by putting an include directive of sys/param.h 
into sys/proc.h and sys/ucred.h, but that is extremely hard to turn into
a patch for the wine package. ;)
