problem cross-compiling gcc 3.4.3 from x86/linux to ppc604/vxWorks

[Jean-François Morcillo]

Hello,
First, let me apologize for my poor English.

As said in the subject, I can't achieve to cross-compile gcc...

1- I used the following command to both configure and compile:

../gcc-3.4.3/configure --prefix=/home/jf/cross --program-prefix=powerpc-
wrs-vxworks- --with-cpu=604 --target=powerpc-wrs-vxworks  --with-
sysroot=/home/jf/Desktop/gcc/VXWORKS --enable-languages=c,f77 2>&1 | tee
gcc-configure.log ; make  2>&1 | tee gcc-make.log 

2- After a while I get the following error:

if [ -f stmp-dirs ]; then true; else touch stmp-dirs; fi

3- I looked into the vxCpu.h file an found:
#if !defined(__CPU__) || !defined(__CPU_FAMILY__)
#error CPU is not defined correctly
#endif

4- I tried to add (I know it's durty ;-)
#define PPC604          94 
#define CPU_FAMILY      90
just before the #if but things didn't get fine... 
What is really confusing me is that I received the same error later in
the build process

Can anybody tell me what a mess I'm folling into ?
