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. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
