   glsl gl_LightSource array must be redeclared
  HelloI have some problems compiling this (Vertex) program on my ATI x1600.vec4 GetLight(int iLightID){return gl_LightSource[iLightID].ambient;}void main(){//gl_FrontColor = gl_LightSource[0].ambient;gl_FrontColor = GetLight(0);gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;}The error i get is:ERROR: 0:3: '[' :  array must be redeclared with a size before being indexed with a variableERROR: 1 compilation errors.  No code generated.As gl_LightSource is a built-in uniform variable one would think it should work anyway and it should know it's own size. If i try to redeclared it with a size it tells me that 'gl_LightSource' : reserved built-in name :(. I also tried the code with the 3DLABS GLSL Validator it say the code is good.Anyone have any ideas why my ATI card hate the code :( ?.   
  I am having exactly the same problem with my Radeon x600 - does anyone know whats wrong? I'm assuming it is a harware specific glsl implementation issue, is there anywhere were you can find information on this I can't find much on the ATI developer site, but perhaps you need to be a registered ati developer or something...If you access the gl_LightSource array with a constant value, it works ie:  gl_LightSource[5].linearAttenuation works fine, but   gl_LightSource[x].linearAttenuation does not.
