Normally if you build gcc on a 64-bit host it will automatically be configured to generate 64-bit code. If you are building gcc on a 32-bit x86 host, you can use the configure option --enable-targets=all to include support for 64-bit x86. See the installation documentation. You can also use --target but for various reasons that is harder. Ian
