>Description:
	USE_GCC=3.2+ on a 6-CURRENT system prefers the GCC 3.2 compiler
	instead of the GCC 3.4 default system compiler.
	One often uses USE_GCC=3.2+ to enable a port to build on RELENG_4,
	but that does not mean a 6-CURRENT user doesn't want to use the
	native compiler.
	I also argue that the correct algorithm for USE_GCC=3.2+ is:
	1. Use system compiler if it's version is allowable by the USE_GCC
	   invocation.
	2. Prefer the highest version # found already installed and allowed
	   by the USE_GCC invocation, rather than the lowest.
	3. Install the specified GCC version and use if, if no other already
	   installed compiler meets the USE_GCC invocation.
