Error building GCC 3.0.4 on RedHat 7.2

[spela vintar]

Dear helpers,
I'm trying to install gcc 3.0.4 on my RH7.2 box. After successful
configure, make bootstrap exits after issuing the following messages
(see below). It might be a trivial thing, I kindly ask for
beginner-friendly help.
Cheers,
Spela
