I just installed the updated kernel packages for centos 4.4 from the centosplus repository. When I run vmware-config.pl to rebuild the vmware modules, it warns me that the kernel was compiled with gcc 3.4.6, whereas my compiler is gcc 3.4.5, and recommends that I not rebuild the modules unless I have exactly the same compiler version. I ignored this and built the modules anyway and they work fine, but why are the plus kernels not built with the stock centos4 compiler suite?
