A project has been formed to provide support for the gcc 4.x and GCC for SPARC Systems (GCCfss) series of compilers in OpenSolaris. The project is focused on two aspects. First is the actual compilers --- getting them supported and integrated in Solaris. The second is the code changes to Solaris which are needed because of the lanugage differences between gcc3.x and gcc4.x.
