Can't compile GLAD for GLES 2.0; redeclared as different kind of symbol
Trying to compile a simple OpenGL application with GLAD, but I get a ton of warnings about things being "redeclared as a different kind of symbol".

Here are my settings on the online generator:

Language: C/C++
GL: None
GLES1: None
GLES2: 2.0
GLSC2: None
Specification: OpenGL
Profile: Compatability
No extensions.
Generate a Loader is checked, the other two checkboxes are not.

This happens with a completely empty main.c that does nothing but `#include "glad/glad.h"` and immediately `return 0;`. Replacing the ES 2.0 version with 3.3 causes it to compile perfectly.
