Something wrong with umass.c on RELENG_4 ?
I've been trying to recompile my kernel lately, but always gave me this error :

cc -c -O -pipe  -Wall -Wredundant-decls -Wnested-externs
-Wstrict-prototypes  -Wmissing-prototypes -Wpointer-arith -Winline
-Wcast-qual  -fformat-extensions -ansi  -nostdinc -I- -I. -I../..
-I../../../include -I../../contrib/dev/acpica -I../../contrib/ipfilter
 -D_KERNEL -include opt_global.h  -mpreferred-stack-boundary=2
