Some small fixes to get things compiling on solaris with cmake.

Some small fixes to get things compiling on solaris with cmake.
There are also some changes that need to be done to libmv but I'm
leaving those out so I can get it patched upstream first.

(Only works with gcc/g++ if we want to use sun's compiler we would need
to get rid of all of our annonymous structs which I don't think
we want to do at this point, example:

typedef struct wmNDOFMotionData {
        union {
                float tvec[3]; // translation
                struct { float tx, ty, tz; };   // this would need to be fixed
		// something like this or something similar:
                struct { float x, y, z; } t;
                };
...
)
