编译过程：
CC=arm-linux-gcc ../glibc-2.3.6/configure --host=$TARGET --prefix="/usr" --enable-add-ons --with-headers=KERNEL_PATH/include
结果在configure时就已经通不过。
显示"forced unwind support is required"
最后建立了一个config.cache文件内容如下：
libc_cv_forced_unwind=yes
libc_cv_c_cleanup=yes
libc_cv_arm_tls=yes
libc_cv_gnu99_inline=yes
配置的命令改为：
CC=arm-linux-gcc ../glibc-2.3.6/configure --host=$TARGET --prefix="/usr" --enable-add-ons --with-headers=$KERNEL_PATH/include
--without-selinux --cache-file=config.cache
KERNEL_PATH指向的是从本站下载的linux2.6.32的代码目录，已make menuconfig.
这时提示：找不到asm/unistd.h
我把includde／linux里的文件（unistd.h在该目录里)拷到includde／asm目录。结果还是不行。我发现在.configure时总是显示找不到unistd.h
.
以下是.configure时的内容：
........

请问这是怎么回事？
