I tried this, but got the same flex error. So I took out the symlinks  
and went back to building seperately. I seem to have found the magic  
combo: the trick is to configure gmp with

./configure ABI=32

and mpfr with the CFLAGS settings gmp picks, which on my machine gives:

./configure CFLAGS="-m32 -O2 -fomit-frame-pointer -mtune=k8 -march=k8"

The standard make/make install puts the binaries in /usr/local/lib  
where the gcc build will find them.


 From there it was reasonably straightforward and I am pleased to  
report that I am now building gcc 4.3 successfully and have a working  
powerpc toolchain. I have built the virtex BSP, but had to fix a  
couple of things: in both libcpu/powerpc/ppc403/console/console405.c  
and libcpu/powerpc/ppc403/tty_drv/tty_drv.c

#include "../ictrl/ictrl.h"

should be:

#include "../irq/ictrl.h"

I look forward to being able to develop an up-to-date BSP for the  
PPC405...
