building gcc3.0 bootstrap cross-compiler missing header files!

[Wang Yonghao (Leo)]

Hello experts

I'm trying to build a cross-compiler host on i686-linux target to 
powerpc embedded board. I'm using below packages:
    binutils-2.12.tar.bz2
    gcc-core-3.0.tar.gz
    gcc-3.0.tar.gz
    glibc-2.2.5.tar.gz
    glibc-linuxthreads-2.2.5.tar.gz
    linux-2.4.18
After read several howtos, binutils is built ok.  When I'm going to 
build gcc-core to a bootstrap c compiler, it failed:

I've tried several combination of configuration switchs.First I tried:
"--with-newlib --without-headers --enable-languages=c --disable-threads"

Then I tired:
"--with-headers=/root/source/linux-2.4.18/include --with-newlib 
--enable-languages=c --disable-threads"
That linux tree I've configured for powerpc and "make dep", thus the asm 
is link of "asm-ppc" and  header files should be prepared for powerpc 
target.

I even tried to extract proper linux header files to prefix path.  
However all of above attempt failed at:

/root/source/gcc-3.0/gcc/config/rs6000/linux.h:81:20: signal.h: No such 
file or directory
/root/source/gcc-3.0/gcc/config/rs6000/linux.h:82:26: sys/ucontext.h: No 
such file or directory
make[2]: *** [libgcc/./_muldi3.o] Error 1
make[2]: Leaving directory `/root/objdir/gcc-3.0/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/root/objdir/gcc-3.0/gcc'
make: *** [all-gcc] Error 2

It seems some libc header files needed. But I really don't know how to 
handle it. And howtos have not mentioned about that. Does anybody can 
give me some clue. Any suggestion will be high appreciated!
