Which shader compiler does Ogre use?

Does it use fxc or just cgc or a combination of both depending on the file? I'm trying to track down the cause of some shader errors..

It uses the cg runtime API v3.1

Ogre doesn't use a stand alone shader compiler like cgc or fxc, it uses the cg/opengl/directx libraries.
DirectX 9 HLSL shaders are compiled by calling D3DXCompileShader().
DirectX 11 HLSL shaders are compiled by calling CreateVertexShader(), CreatePixelShader(), CreateGeometryShader(), CreateDomainShader() or CreateHullShader() (members of ID3D11Device).
GLSL shaders are compiled by calling glCompileShaderARB().
CG shaders are compiled by calling cgCreateProgram().

Ah ok. Good to know. Thanks Kojack. Since you seem pretty knowledgeable about shaders, can you tell me where the errors I describe here come from? http://www.ogre3d.org/forums/viewtopic.php?f=2&t=80873
