Somehow you're getting old or non-default settings, i.e. the '-O -mcpu=pentiumpro'. This is what happens when you have CPUTYPE=p3 and default settings: cc -c -O -pipe -march=pentium3 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -fformat-extensions -std=c99 -g -nostdinc -I- -I. -I/usr/src/sys -I/usr/src/sys/contrib/dev/acpica -I/usr/src/sys/contrib/altq -I/usr/src/sys/contrib/ipfilter -I/usr/src/sys/contrib/pf -I/usr/src/sys/contrib/dev/ath -I/usr/src/sys/contrib/dev/ath/freebsd -I/usr/src/sys/contrib/ngatm -D_KERNEL -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -mno-align-long-strings -mpreferred-stack-boundary=2 -ffreestanding -Werror aic79xx_reg_print.c Note nothing (in fact, double space) before the -mno-align-long-strings. Here's what happens if you set CONF_CFLAGS=-DFOO: cc -c -O -pipe -march=pentium3 -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual -fformat-extensions -std=c99 -g -nostdinc -I- -I. -I/usr/src/sys -I/usr/src/sys/contrib/dev/acpica -I/usr/src/sys/contrib/altq -I/usr/src/sys/contrib/ipfilter -I/usr/src/sys/contrib/pf -I/usr/src/sys/contrib/dev/ath -I/usr/src/sys/contrib/dev/ath/freebsd -I/usr/src/sys/contrib/ngatm -D_KERNEL -include opt_global.h -fno-common -finline-limit=8000 --param inline-unit-growth=100 --param large-function-growth=1000 -DFOO -mno-align-long-strings -mpreferred-stack-boundary=2 -ffreestanding -Werror /usr/src/sys/cam/cam_xpt.c i.e. it's added precisely where your bogus arguments appear.
