clfs ubuntu8.10 编译gcc4.3.2报错，请大家帮帮忙

各位达人：
我在自己的宿主平台上使用的是ubuntu8.10，32位的。作clfs时（x86_64）,在编译binutils时遇到错误，后来把宿主内的gcc-4.3.2换成了gcc-4.1，编译通过，但是当编译gcc-4.3.2的包时，出现错误，如下：

gcc -c -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -Wmissing-format-attribute -Wno-overlength-strings -pedantic -Wno-long-long -DHAVE_CONFIG_H -I. -I../../gcc-4.3.2/fixincludes -I../include -I../../gcc-4.3.2/fixincludes/../include ../../gcc-4.3.2/fixincludes/fixincl.c

不知道这个错误如何解决，希望有人知道一下，谢谢了。

第几章？第几节？

哪个版的手册？

前面执行过什麽？
