hi,

i'm having problems compiling a new kernel. relevant parts of the config
are:
options         SYSVSHM
options         SHMMAXPGS=524288
options         SHMSEG=64
options         SYSVSEM
options         SEMMNI=80
options         SEMMNS=480
options         SEMMNU=240
options         SEMMAP=240
options         SYSVMSG
(this is for jailed PGSQL),

options         IPFILTER
options         IPFILTER_LOG
options         PFIL_HOOKS
(this is to redirect to jail, etc. PFIL_HOOKS was added after some
googleing).

kernel compiled without problems with PGSQL tunings, without IPFILTER
part.

error message is:
cc -c -O -pipe -mcpu=pentiumpro -Wall -Wredundant-decls -Wnested-externs
-Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline

anyone have a clue?
