Created attachment 33290 [details] Log from XreaL The game XreaL does not work with Mesa, one of the shaders refuse to compile with the following message: "Error: declaration of 'NL' conflicts with previous declaration". I'm attaching a log from the game which includes the shader source. I'm using git master, db18996d3da4009a7a031e3444b5cd688e12dc22.
The bug was in the GLSL preprocessor. It's been fixed in the Mesa 7.7 branch with commit 2eedbc94c22bc13575e7639620f0d1957f205b34 and Mesa/master with commit ee67167358e91e9ffde8aa9e5b96e5def4c16904.
