【求助】gcc2.95make过程报错

happyg

linux版本：
Red Hat Enterprise Linux Server release 5.1

通过configure编译成功：
../gcc-2.95/configure --prefix=/opt/powerpc-linux --enable-threads=posix --disable-checking --enable--long-long --host=i686-redhat-linux --with-system-zlib --enable-languages=c,c++

但是在make过程中就出现如下错误：
In file included from /usr/include/sys/types.h:270,
                 from /usr/include/stdlib.h:438,
                 from ../../gcc-2.95/gcc/frame.c:42:

make: *** [all-gcc] Error 2

请问有没有人知道怎么解决？？
谢谢
