Problems compiling GCC3.0 for powerpc-elf target on X86 linux

Looking for a little help..
I'm attempting to build the GCC3.0 cross compiler 
for the powerpc-elf target on a native X86 Red Hat 7.0 Linux box. 
I'm using the following:
GCC - 3.0
binutils - 2.10.1
newlib - 1.9.0
gdb - 5.0
TARGET = powerpc-elf
PREFIX = /usr/local/powerpc-elf
Common build directory for gcc, binutils, newlib - 
GCC Source dir - 
Thusfar I have run into two problems, both during 
the complete full build of GCC (binutils, bootstrap gcc, and newlib all built 
fine.. I have not yet built the debugger.. ) 
The first problem was with vsprintf.c in libiberty. 
Command line and error as follows:
-B/home/mlancisi/build_binutils/gcc/ -B/usr/local/powerpc-elf/powerpc-elf/bin/ 
-B/usr/local/powerpc-elf/powerpc-elf/lib/ -isystem

-I. -I../../../gcc-3.0/libiberty/../include  -W -Wall -Wtraditional

To get around this issue, based on some info 
obtained in the crossgcc mailing list archives, I simply stubbed out vsprintf.c 
(ifdeffed out actually) . I was unable to find powerpc-elf header files which 
likely would have also fixed the problem.. I think I should be all set here 
because I believe vsprintf is available in the standard lib... If anyone knows 
different, please let me know!!! 
Second issue - Once vsprintf was stubbed out, the 
build continued on until it got to another problem, mentioned more recently in 
the archives, as follows:

I found the recent discussion in the archives 
regarding this issue as pertains to the powerpc-eabi cross compiler. The 
question is, is there a generic fix for this as yet? Or a workaround? I'd 
rather not have to  go back to GCC 2.95.3 to build the powerpc-elf cross 
compiler, as we use the newly released GCC3.0 for our native 
Thanks in advance for ANY help!!
