gcc-3.1 compilation breaks

[Fernando <fernando at elec dot gla dot ac dot uk>]

Sorry if this is a stupid question; but I couldn't find the answer to it 
anywhere.

I am trying to build gcc-3.1 in a powerpc running mandrake 8.2.  I did the 
following:

0- Upgraded binutils to binutils-2.12.90.0.14

1- Downloaded and expanded gcc.  Created an objdir directory to build it.

2- cd objdir; and configure it:

../gcc-3.1/configure --program-suffix=-3.1 --enable-altivec 
powerpc-*-linux-gnu*

3- make bootstrap

After a while, I get the following error:

Making all in libmath
make[4]: Entering directory 
`/home/fernando/GCC/objdir/powerpc-*-linux-gnu*/libstdc++-v3/libmath'

Please help!

I am not in the list; so I would be very grateful if you could CC to me any 
replies.
