You will run into issue when mixing C++ and ObjC code from the gccXX family with other compilers (as is being discussed in another thread), but as of a few weeks ago, there should be no reason that mixing +gcc47 and +gcc48 variant builds should not work.  If you just don't like having multiple compiler versions available, that's obviously a separate issue and hopefully default_variants will get updated soon =).

Yes. But updating the default_variants is not designed to have any effect on users who already installed the port with the old defaults, unless they take deliberate steps to rebuild with the new defaults, such as the script I posted a few messages ago.
