>Organization:
Universidad del Pais Vasco - Dept. de Electricidad y Electronica
>Environment:
FreeBSD haddock.we.lc.ehu.es 4.4-RELEASE FreeBSD 4.4-RELEASE #2: Sat Oct  6 20:43:56 CEST 2001     toor@haddock.we.lc.ehu.es:/usr/obj/usr/src/sys/HADDOCK  i386

>Description:

The recently committed em(4) driver breaks kernel compilation when only the
src-sys collection (AKA "kernel developer" distribution) is installed, since
sys/dev/if_em.h includes stddef.h.

>How-To-Repeat:

On any system with only src-base and src-sys collections installed:

# cd /usr/src
# make buildkernel
...
===> em
@ -> /usr/src/sys
machine -> /usr/src/sys/i386/include
perl @/kern/makeops.pl -h @/kern/device_if.m
perl @/kern/makeops.pl -h @/kern/bus_if.m
perl @/kern/makeops.pl -h @/pci/pci_if.m
touch opt_bdg.h
rm -f .depend
mkdep -f .depend -a   -nostdinc -D_KERNEL -DKLD_MODULE -I- -I. -I@ -I@/../include -I/usr/obj/usr/src/i386/usr/include  /usr/src/sys/modules/em/../../dev/em/if_em.c /usr/src/sys/modules/em/../../dev/em/if_em_fxhw.c /usr/src/sys/modules/em/../../dev/em/if_em_phy.c
