There are currently several warnings when building libsoy. One of them looks like this:

libsoy/src/materials/Textured.gs: In function ‘soy_materials_textured_real_enable’:
libsoy/src/materials/Textured.gs:79:3: warning: passing argument 3 of
 ‘glShaderSource’ from incompatible pointer type
             glShaderSource(_vertex_shader, 1, vertex_shader, {-1})

This can be solved in either our own gles-2.0.vapi or our use of this function in the .gs files. Either way, silence this warning.
