While building 6-CURRENT kernel with 'make buildkernel' I has a lot of
warnings like:

cc -c -O -pipe  -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 -O -mcpu=pentiumpro -mno-align-long-strings -mpreferred-stack-boundary=2 -ffreestanding -Werror  vers.c
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.

% fgrep -r  mcpu /usr/share/mk
/usr/share/mk/bsd.cpu.mk:_CPUCFLAGS = -mcpu=ev4 -mtune=ev5
/usr/share/mk/bsd.cpu.mk:_CPUCFLAGS = -mcpu=${CPUTYPE}
/usr/share/mk/bsd.cpu.mk:#XXX: gcc doesn't seem to like -mcpu=xscale, and dies while rebuilding itself
/usr/share/mk/bsd.cpu.mk:#_CPUCFLAGS = -mcpu=xscale
/usr/share/mk/bsd.cpu.mk:_CPUCFLAGS = -mcpu=${CPUTYPE}
% fgrep CPU /sys/i386/conf/VBOOK 
cpu             "I686_CPU"              # aka Pentium Pro(tm)
%

Is it ok for modern builds ?
