Errors cross compiling gcc 4.1.1 for i686-linux-pc

[Klaus Nji <makaveli_0000 at yahoo dot com>]

Need help here cross compiling gcc 4.1.1 for i686 linux pc target on cygwin 1.5.23.

I was able to compile and install binutils 2.13.1 without incident.  I also current have gcc 3.4.4 installed.  Any suggestions?

The logs show:
