内核2.6.3, make menuconfig时出错！

In file included from /usr/include/signal.h:358,
                 from /usr/include/sys/wait.h:30,
                 from scripts/kconfig/mconf.c:10:
/usr/include/bits/sigthread.h:36: error: syntax error before "__threadid"
make[1]: *** [scripts/kconfig/mconf.o] 错误 1
make: *** [oldconfig] 错误 2

xconfig也是一样，之前已经做过make mrproper

自问自答：

我很久很久以前修改过几个头文件，现在把它该了回来了。
