The value of gl_MultiTexCoord(0-2) will vary.

Its value is the mapping type set in the material panel.

for each texture 0-2 if the value is:

• UV - uv texture coordinates assigned to the mesh.
• Orco-Glob - vertex position
• Tangent - tangent space vector

If you have two textures and you want the uv coordinates for the first texture and the tangent vector for the second texture: set the buttons in the material panel accordingly and you have

gl_TexCoord[0] = gl_MultiTexCoord0; // UV
gl_TexCoord[1] = gl_MultiTexCoord1; // Tangent
...
