gcc3 install falure

[david d]

 Hello  
I use RedHat Linux7.3 on a P-3 computer. i've  
recently downloaded gcc3.1.1 source and tried  
to compile it on my machine, keeping the  
older version of it.  
I've put the sources into  
/home/phr/temp/gccc/gcc-3.11 (srcdir),  
created /home/phr/temp/objdir (objdir),  
then I did :   
cd /home/phr/temp/objdir  
sudo /home/phr/temp/gccc/gcc-3.11 configure   
--program-suffix=3  
sudo make bootstrap-lean CFLAGS='-O'  
LIBCFLAGS='-g -O2' LIBCXXFLAGS='-g -O2  
-fno-implicit-templates'   
  
and then after lots of time, I get the  
following:   
make[3]: Leaving directory  
`/home/phr/temp/objdir/gcc'  
make[2]: Leaving directory  
`/home/phr/temp/objdir/gcc'

What could be wrong
