Can this also help the CC, CPP, CXX situation?

I mean: there are many ports that say things like this:

platform darwin 8 {
	configure.env CC=/usr/bin/gcc-4.0 CPP=/usr/bin/cpp-4.0 CXX=/usr/bin/g 

Why is this necessary? Wouldn't all three of those be the default on  
darwin 8 anyway? What problem are these directives trying to solve?  
And could the problem be solved at a global MacPorts level instead?
