[PATCH] Compilation Warnings OSX 10.9.5 (Mavericks)

[Stan]

When building the game from the terminal (make in gcc folder) I get those warnings.

../../../source/simulation2/components/CCmpPathfinder.cpp:44:11: warning: 
      unused variable 'DEFAULT_MOVE_COST' [-Wunused-const-variable]
const int DEFAULT_MOVE_COST = 256;

      unused variable 'WAYPOINT_ADVANCE_LOOKAHEAD_TURNS'
      [-Wunused-const-variable]
static const int WAYPOINT_ADVANCE_LOOKAHEAD_TURNS = 4;

The first two ones are important, and I included the others in case they have any influence.

[Stan]

Remove the two unused consts.

[historic_bruno]

That was one I wanted to ask itms about but never got around to it. Are the variables really obsolete or placeholders for some missing functionality?

[Stan]

They are the legacy of the old code so id say obqolete. Itms told me I could remove them :)
