configure error on OpenBSD

[Vortechz Anderson]

I am trying to port wine to OpenBSD, or at least
trying to make it build and not segfault upon
execution...

(This bug is a minor issue compared to some ld.so
trouble I have run into. I'd be happy to know about
differences between Net/Free/OpenBSD ld.so)

configure output:

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

configure: WARNING:     ##

Some rows from config.log:

                 from conftest.c:106:

I managed to get around this by including
sys/param.h in the sys/proc.h and sys/ucred.h headers
but I'm not sure that's the right approach. Wine
developers wouldn't benefit from such patches anyway.

I have tried to change configure.ac properly but it
seems that I can't get it right...

// V.A.

P.S.

Adding sys/proc and sys/ucred to header list and
checking for param.h dependency is not sufficient:

AC_CHECK_HEADERS([sys/proc.h],,,
    [#if HAVE_SYS_PARAM_H
     # include <sys/param.h>
     #endif])

AC_CHECK_HEADERS([sys/ucred.h],,,
    [#if HAVE_SYS_PARAM_H
     # include <sys/param.h>
     #endif])

With these addons, both proc and ucred fails.
D.S.
