 Thanks for your attempts. I think first priority would be to make the 
 thing running. Warnings are not taken particularly important.

 First, since this failed, could you retry by building in a separate 
 build-directory, as the installation instructions recommend? I.e., if 
 gcc-3.2.1 is you src dir, then make a parallel directory build and call
   ../gcc-3.2.1/configure --...
   make bootstrap
 
 Also, what happens if you don't specify CFLAGS et al? As far as I know the 
 stage2 build already uses optimization flags, so there is no need to also 
 use them for the first two stages (apart from possibly tripping your 
 bootstrapping compiler).
 
 Thanks
   Wolfgang
