Hi Harshal. I'm no expert, but GCC can be built by another C compiler. If you have a look at how GCC builds you'll see that it goes through a few stages - the first is where the local C compiler builds a first version of GCC, and then this new version of GCC is used to build itself. The same technique is used to build newer versions of GCC. If your machine currently has GCC version 3 and you want to build version 4 then the first step uses GCC 3 to build a temporary version of GCC 4, and then this temporary version is used to build the final version.
