[FIXED] Error while compiling on a Mac

[SamJBarney]

So I've started the Component Rewrite, finally have the time, and I get this error when I try to compile my code:

In file included from /Volumes/Storage/dev/MCServer/src/Mobs/AIAgresssiveComponent.cpp:1:

/Volumes/Storage/dev/MCServer/src/./ChatColor.h:12:15: error: use of undeclared identifier 'std'

I'm sure I am missing something really simple that I need to be doing. What am I missing?
