powerpc-linux gcc build error

[Ganesh.Tawde@relianceinfo.com]

Hi,

I am trying to build a cross compiler toolset for powerpc-linux on a RH9
Linux machine. The binutils builds fine. When it comes to building the gcc
core, I get the following error. I m using gcc-3.4.0, binutils-2.14,
glibc-2.3.2 and glibc-linuxthreads-2.3.2.

Googling on this error gave me some results with similar error faced before
by many people but could not find a proper solution.
I am using the build procedure as listed in

http://www.pages.drexel.edu/~sg64/stuff/cross-compile.htm

and also this one

http://www.cs.duke.edu/~irwin/gcc_ppc.html

and also referring to Bill Gatliff's script.

I also tried copying signal.h from other folders but still get errors as
the build proceeds.

Any help would be appreciated.

Rgds,
Ganesh
