There are a lot of compilers available to build our packages (i.e. GCC 2.95, 3.0.4, 3.1, 3.1.1, ICC, etc.). It's not possible to compile sources with all the compilers available. I know that the variable "KEYWORDS" is being used to define for which platform the involved package is. I think it would be very handy if this variable or a new one will be used to define which compiler can be used. I someone wants to have a purely 3.1.1 system, he/she won't be able to see the packages that won't compile with 3.1.1. If a user still wants to install the package then portage is able to compile this package and all dependencies with an other version (if possible next to the higher version).
