Problem with libiberty while building a i686-Linux --> powerpc-aix4.3 cross-compiler

[John McClenning <johnm at typotronics dot com>]

All,

  I'm trying to build a i686-Linux to powerpc-aix4.3 cross-compiler. I have 
downloaded the tar balls for binutils, gcc, gdb and newlib. I ran the 
one-tree-1.6.sh script and then tried to build the cross-compiler by 
running the build-cross.sh script.

  I've had a few stumbling blocks along the way which I was able to solve, 
but I can't seem to get past this one.

output from build-cross.sh

--------------------------------------

  I'm assuming that the header files it's looking for are the ones that I 
copied from the AIX box. and placed in my 
'/home/johnm/cross-comp/powerpc-aix4.3/include/' directory. I don't 
understand why it can't find them.

  Looking at the config.log in the libiberty directory shows the following 
warnings and errors.

  Can someone tell me what I'm missing or point me in the right direction 
so I can find it myself?

TIA
