我升级gcc到3.4.3并修改了/etc/make.conf （请看贴内详细内容）

gklive

我用gentoo2005.0 stage3 pentium3来安装，我的CPU是pentium-m，所以我一开始就得新编译gcc
emerge gcc-config glibc binutils gcc
（因为要编译好基本的toolchains还要编译一次）
第二次进行emerge glibc binutils gcc portage时（当然我这时已经修改了/etc/make.conf
CFLAGS="-O2 -march=pentium-m -mtune=pentium-m -fomit-frame-pointer -pipe"
CHOST="i686-pc-linux-gnu"
CXXFLAGS="${CFLAGS}"  并且env-update && source /etc/profile后才开始第二次编译gcc的）但是我看见其中的信息是

i686-pc-linux-gnu-gcc gconv_open.c -c -std=gnu99 -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -mtune=pentium-m -mtune=pentium3 -pipe -mpreferred-stack-boundary=2 -g -I../include -I. -I/var/tmp/portage/glibc-2.3.4.20050125-r1/work/build-default-i686-pc-linux-gnu-nptl/iconv -I.. -I../libio -I../nptl -I/var/tmp/portage/glibc-2.3.4.20050125-r1/work/build-default-i686-pc-linux-gnu-nptl -I../sysdeps/i386/elf -I../nptl/sysdeps/unix/sysv/linux/i386/i686 -I../nptl/sysdeps/unix/sysv/linux/i386 -I../nptl/sysdeps/unix/sysv/linux -I../nptl/sysdeps/pthread -I../sysdeps/pthread -I../nptl/sysdeps/unix/sysv -I../nptl/sysdeps/unix -I../nptl/sysdeps/i386/i686 -I../nptl/sysdeps/i386 -I../libidn/sysdeps/unix -I../sysdeps/unix/sysv/linux/i386 -I../sysdeps/unix/sysv/linux -I../sysdeps/gnu -I../sysdeps/unix/common -I../sysdeps/unix/mman -I../sysdeps/unix/inet-I../sysdeps/unix/sysv/i386 -I../sysdeps/unix/sysv -I../sysdeps/unix/i386 -I../sysdeps/unix -I../sysdeps/posix -I../sysdeps/i386/i686/fpu -I../sysdeps/i386/i686 -I../sysdeps/i386/i486 -I../nptl/sysdeps/i386/i486 -I../sysdeps/i386/fpu -I../sysdeps/i386 -I../sysdeps/wordsize-32 -I../sysdeps/ieee754/ldbl-96 -I../sysdeps/ieee754/dbl-64 -I../sysdeps/ieee754/flt-32 -I../sysdeps/ieee754 -I../sysdeps/generic/elf -I../sysdeps/generic -nostdinc -isystem /usr/lib/gcc/i686-pc-linux-gnu/3.4.3-20050110/include -isystem /usr/include -D_LIBC_REENTRANT -D_LIBC_REENTRANT -include ../include/libc-symbols.h -DPIC -o /var/tmp/portage/glibc-2.3.4.20050125-r1/work/build-default-i686-pc-linux-gnu-nptl/iconv/gconv_open.og -MD -MP -MF /var/tmp/portage/glibc-2.3.4.20050125-r1/work/build-default-i686-pc-linux-gnu-nptl/iconv/gconv_open.og.dt -MT /var/tmp/portage/glibc-2.3.4.20050125-r1/work/build-default-i686-pc-linux-gnu-nptl/iconv/gconv_open.og

在一开始处竟显示i686-pc-linux-gnu-gcc gconv_open.c -c -std=gnu99 -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings -mtune=pentium-m -mtune=pentium3 -pipe -mpreferred-stack-boundary=2 -g -I../include -I.
为什么这时的-mtune=pentium3的？？我的/etc/make.conf里已经没有pentium3啦
