The answer depends on what your new machine is, and the operating system it runs. For example, if your new machine is a Playstation 3 and your operating system is Yellow Dog Linux, the GCC compiler is provided as part of the distribution. You can install that GCC compiler, download the GCC source, and then compile your own GCC compiler using the distribution's GCC compiler. You might wonder "Why would I compile my own, if I can install theirs?" One reason is if theirs is GCC 3.3.2, and you want to use the active development head GCC 4.3.0, then that would be one use case. Or another use case scenario, if they provide GCC 4.2.0, and you need to target GCC 3.1 for your product because it is a binary SDK which needs to use an older compiler for distribution reasons. Or another use case is that you only trust things you build. Or just for the educational experience. HTH, --Eljay
