Yes.  In the above, lang/gcc will track GCC 4.7 releases whereas
lang/gcc47 will track GCC 4.7 snapshots.

The lang/gcc4x ports always have been tracking snapshots until that
release went EOL upstream at which point they moved to the final
release on that branch.

lang/gcc is there to track releases and receive as few updates as
reasonably possible. 

In other words, lang/gcc is the default port to use.  lang/gcc4x
shall be used when specifically necessary (newer version of GCC
required) or by those familiar and comfortable with newer versions.
