Creating objects in wings3D gives a mesh2 object which has a texture
section. It seems to require a texture in this otherwise it won't render and
I have a material I want to give to the material. Is there a way to give the
mesh a material which ignores the texture defined in the mesh thing? Doing
"object{blah material{mesh_mat}}" has no effect.

You can only use textures with mesh2.
If you want to use a material, I presume it's because
it has an interior.
You can use interior with mesh2 simply including it:

texture { ...whatever... }
interior { ...whatever... }

Hope this helps.

Tried it, that don't work...
#declare LCornea_1=
   texture{
     pigment{eyepigment}
   }
   texture{
     pigment{p_map8}
     normal{p_map9}
     finish{phong 1.00 phong_size 66 reflection{0.25 metallic}}
   }
   interior{
     ior 1.5
   }

Gives a Parse Error: Expected 'object or directive', interior found 
instead.  Remove the interior{} and it works.

You need to add the interior statement at the end.

#declare MyMesh=mesh2{...}

object{MyMesh interior{...}}

The way it worked for me with wings3D is:

#declare some_object = mesh2 {
vertex_vectors {....}
normal_vectors {....}
texture_list {	2,//the number of textures
    	texture { one_texture }
    	texture { texture_that_needs_interior }
}
face_indices {....}
normal_indices {....}
interior {some_Interior}
}

Of course it does. You use the syntax for a layered texture declaration, 
but put an interior statement at the end. You need to put the interior 
in the object itself.
The reason that you can't specify a per-triangle material is that the 
material has an interior, and having different triangles of the same 
mesh with different interiors does not make sense.

The documentation says that materials are nothing more than "container
objects" for textures and interiors (so that both can be contained in one
object). That seems to imply that materials are allowed anywhere that
textures and interiors are allowed.

So, if materials aren't allowed in meshes, that might be a bug. (?)

You can't put interiors in mesh triangles either. It's not a bug.
