>Description:
        The kernel compilation fails with "bsd_to_linux32_ipc_perm() defined 
but not used" message,
        if linux32-compat is configured but no SYSV-SHM and SYSV-SEM.
        The problems is located in the file 
/usrsrc/sys/compat/linux32/common/linux32_ipccall.c.
>How-To-Repeat:
        Setup a kernel configuration without SYSV-IPC but linux32-compat and 
try to compile it.
>Fix:
        The following patch solves the problem:
