UNITY preprocessor define

gistfile1.txt

It's just a simple preprocessor define for Unity itself.
Use case: If I'm building the same piece of code both in Unity and in XNA/Monogame/regular C# sometimes I want to do something different on each 'platform'.

A mediocre but to the point use case:
void f() {
#if UNITY
    UnityEngine.Debug.Log("f");
#else
    Console.WriteLine("f");
#endif
}

The whole reason for wanting it in 4.6.x is eventually we will be supporting the last release of Unity 4, and all releases of Unity 5. (Much like we supported Unity 3.5.7 and Unity 4 up until earlier this year.)
If it doesn't land in 4.x then the timeline for us being able to actually make use of it results in the 'feature' being worth quite a bit less.

Right now we do use the gmcs.rsp / smcs.rsp files for internal stuff but that is hard to ship to partners.
So we end up with:
#if UNITY_3_5 || UNITY_4_0 || UNITY_4_1 || UNITY_4_2 || UNITY_4_3 || UNITY_4_5 || UNITY_4_6 || UNITY_5_0
#define UNITY_BUILD
#endif
