That compiler is rather old. I think there are gcc 4.4 packages for centos.

If you want a recent compiler with a recent userland then centos is not
a good choice,
they are server releases, and stay with old versions of packages for a
long time.
Something like Debian unstable, or Fedora might be a better choice.
