These undefined symbols can be found in the C source files under the 
directory gcc-3.3.2/libiberty

When I did gmake bootstrap, it gave me an error for missing libiberty.a. 
So I copied the file from one of the system lib directory. It seems like 
gcc bootstrap needs to compile those files in gcc-3.3.2/libiberty to 
produce libiberty.a. Is my assumption correct? If yes, how do I make 
libiberty? The Makefile does not have the lines to make libiberty.a

How?--
