Not true. Just as you can choose from multiple self-built kernels
you can build and choose dynamically from multiple self-built GCCs.

E.g., for this particular case, download gcc-4.3.3.tar.bz2, tar jxf it,
mkdir objdir, cd objdir, /path/to/gcc-4.3.3/configure --prefix=/tmp/gcc43
--enable-languages=c, make, make install, cd /path/to/linux-2.6.30,
PATH=/tmp/gcc43/bin:$PATH make, and so on.
