failing to build gcc 3.1 or 3.0.4 on a Linux machine

[Fernando Jeronymo]

I have gcc 2.96 installed in a Red Hat Linux release 7.1 (Seawolf) on this
machine: Linux sablel 2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686 unknown


So, now I downloaded both gcc 3.1 and 3.0.4, and it doesn't matter which one of
them I try to build. I am doing:

$ configure /gcc/3.0.4

then I do:

$ make bootstrap (or just make)


and in the end, I get the following message:

configure: error: please upgrade to GCC 3.0 or above


Any ideas?

Thanks,
Fernando
