Nothing fancy needed. You can use the gcc-4.4.1 release tarball and any recent
gcc-4.3 weekly snapshot tarball, like 4.3-20090830.

I've always seen the bogus errors in the C or C++ testsuites, so to save
some time you can just --enable-languages=c,c++ when building gcc.

The machines I've been running the testsuites on are a mix of architectures
running older or stability-oriented distros:

M1: i686 PC, Fedora Core 6, dejagnu-1.4.4-5.1, expect-5.43.0-5.1, tcl-8.4.13-3.fc6
M2: powerpc64 (G5), YellowDog 6.2, dejagnu-1.4.4-5.1, expect-5.43.0-5.1, tcl-8.4.13-3
M3: ARM, FC8-based, dejagnu-1.4.4-12.fc8, expect-5.43.0-9.fc8, tcl-8.4.17-1.fc8
