Dear everybody,
I'm trying to build gcc-3.1.1 on MacOS 10.1.5 (PowerBook G4).  I am not 
an expert, so please excuse me if I am doing something silly.

I started with

    ../gcc-3.1.1/configure --prefix=/usr/local/gcc-3.1.1 --enable-altivec 
--enable-languages=c,c++

followed by 'make bootstrap'.  The latter failed as follows:

...

I guess there is something wrong with the assembler because the problem 
arises in a .s-file.  Can somebody help me?

Thanks a lot,
Kaspar
