Function signature mismatch

I'm attempting to run Google Dawn code using OpenGL and Emscripten, but ran into a runtime error with signature mismatch. The function is declared as `GLenum glClientWaitSync(GLsync p0, GLbitfield p1, GLuint64 p2)`, its pointer is fetched dynamically. The code I use calls it as `(func (param i32 i32 i64) (result i32)))`, but Emscripten defines it as `(func (param i32 i32 i32 i32) (result i32)))`. Are there any flags I'm missing, or is it a bug in Emscripten or the SDK?

I assume this isn't the only function affected, but it's as far as the program reached
