Couldn't build gcc-20010319 on i686-pc-linux/gnu

[Maurizio Loreti <loreti at pd dot infn dot it>]

I have downloaded today gcc-20010319.tar.gz; after:

# gzip -dc /usr/archive/dist/gcc-20010319.tar.gz | tar xof -
# mkdir objdir && cd objdir
# ../gcc-20010319/configure i686-pc-linux-gnu --prefix=/usr/local/gcc --enable-libstdcxx-v3
.....
# nice make bootstrap

Any hint?  Thank you in advance,	M.

The instructions said to use Windows 98 or better - so I installed FreeBSD.
