C++ map: expected initializer before ‘<’ token

I'm getting this error in a header file:

error: expected initializer before ‘<’ token

class MyEntity;
typedef std::map<uint16,MyEntity*> myList_t;

I figured it's not seeing the map include, but at the top of that header file is:

#include <list>
#include <map>

In another header file:

typedef unsigned int               uint32;

Any ideas?
