configure: WARNING: unrecognized options

[Roberto Nunnari <roberto dot nunnari at supsi dot ch>]

Hi all.

First of all let me say I'm new to gcc building.. I've been trying 
building gcc 4.8.1 for over a full day but keep failing.

I built/installed dependencies and got to the gcc configure step.. and 
here's where it fails.. I get:

configure: WARNING: unrecognized options: --with-gmp, --with-isl, 
--with-cloog


So.. a bit about my environment:

[root@node03 new-gcc]# uname -rms
Linux 2.6.18-274.el5 x86_64

[root@node03 new-gcc]# cat /etc/redhat-release
CentOS release 5.7 (Final)

[root@node03 new-gcc]# gcc --version
gcc (GCC) 4.1.2 20080704 (Red Hat 4.1.2-51)


and here's what I've done:

build/install gcc 4.8.1
==============
# mkdir /root/new-gcc && cd /root/new-gcc

// get gcc
