Its supported in as much as the option is there...

Its not support in the sense there are no guarantees as to whether 
things will work properly if you use it to change the compiler from what 
the portfile has been setup to use by the port maintainer. Specifically, 
forcing the use of gcc to build c++ code is very problematic due to the 
much discussed runtime issues, and consequently very unsupported.
