I didn't see anyone ask this yet so here goes. Why are there both GCC
3.3.2 and GCC 3.2.3 in Fedora????
gcc-3.2.3 is for building the kernel.
Forgive my ignorance, but still -- why?
Because shipping with 3 versions of GCC would have been way too complex. (This is how Mac OS X 10.2.x and Darwin 6.x shipped [GCC versions 2.95, 3.1, and GCC 3.3]). Be glad the Fedora maintainers are keeping things simple.
Among other things, GCC 3.3 removed the deprecated multi-line string literals extension from the preprocessor. This has been used heavily all over the kernel and although it has been cleaned in many places in 2.4.x kernels, it is still present in several places. 2.6.x kernels should build with GCC 3.3.x just fine.
The binaries that are built by the different GCC version are all different and sometimes a program (particularly if it dynamically binds against other libraries or has a plugin interface) is sensitive to the GCC version. The kernel is a great example of this. So are the Sun and IBM java virtual machines.
