That's a fair question -- you just have been a bit too quick while I
have been working on an updated pkg-plist and the commit message. :-)

Basically the purpose is to establish a "preferred" version of GCC for
Joe User and Jane Porter.  And keep rebuilds of that one to a minimum.

On the first, a step on a path towards establishing a preferred version of 
GCC amidst all the flavors, this is similar to the current USE_FORTRAN=yes 
which transparently picks a preferred version of GCC already.  That used 
to be lang/gcc45 and has been upgraded to lang/gcc46 recently after an 
appropriate pointyhat run.

On the second, see PR 156857 for a concrete user request and some
thinking around that.

This port of GCC, lang/gcc, will always correspond to one of the ports 
that are tracking snapshots and conflict with that one, lang/gcc46 for 
now.  As a user, you have the choice to go for the release-based version 
which is only updated every couple of months, or track the current 
snapshot.

PS: And some of the other lang/gcc* ports really need to die.  I
have spent quite some time towards paving that road for lang/gcc34
where lang/objc and some annoying ports around g77 (cad/sceptre
and science/elmer-matc, science/elmerpost) are the major hold offs, 
and lang/gcc44 which we carry exclusively for the sake of cad/salome.
