How to stop shader compiler applying Normalize to normals

I'm trying to use the normals part of the vertex stream for something else other than normals for some procedural animation. It all works fine on the PC version but the iOS version has completely different results and when I opened up the compiled shader I found this line:

tmpvar_1 = normalize (_glesNormal);

Is there some kind of command I can put into the Unity shader to stop the compiler from generating this line?

 

Thanks!

That worked a treat. Is this kind of thing documented anywhere? My searching skills failed me

Bump.
This compile directive was removed in the latest Unity versions. Is there any other way to stop Unity from normalizing mesh vectors?

Since normal and tangent are the only vectors correctly transformed by Unity during batching, we literally have no other way to pass some arbitrary vectors to the shader other than sending them as normal/tangent.

Also:
Similarily, is there a way to stop Unity from normalizing these vectors when importing them from an FBX?

Also #2:
Is there a way to tell Unity to transform normal as a regular vector (non-uniform scale) when batching meshes for a specific shader?
All three questions are actually about the same thing: how to pass multiple vectors to the shader and keep them properly transformed when batching is performed. So I guess it's OK to add the last two here, too.
