one more thing to mention about gcc, is the configurations during their
compilation: (although it may not have much sense as those things were never
really having an effect to the anticipated extent)

../gcc-4.a.b/configure --prefix=/opt/gcc4ab --libexecdir=/opt/gcc4ab/lib
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-clocale=gnu --enable-languages=c,c++ --disable-libstdcxx-pch
--disable-bootstrap --disable-stage1-languages --disable-objc-gc
--disable-libssp --disable-libada --with-gmp=/opt/gmp --with-mpfr=/opt/mpfr
--with-ppl=/opt/ppl --with-cloog=/opt/cloog --with-mpc=/opt/mpc

just in case there were any hope for cloog and ppl for this program I made sure
it was properly included in the compiler, but unfortunately from the tests as
you can see, those options had no effect on nbench
