If you want to have a look at how the package looks : https://github.com/Xemuth/UPP-glad

I have try it with OpenGL example (from reference) by replacing every include glew had by a single #include <glad/glad.h> and it worked well (on windows)
I also changed the MakeWGLContext function :

void MakeWGLContext(int depthBits, int stencilBits, int samples)
{
/*...*/
if(pass == 0) {
	HGLRC hRC = wglCreateContext(hDC);
	wglMakeCurrent(hDC, s_openGLContext);
        if(!gladLoadGL()){
		RLOG("Failed to load all OpenGL functions");
		exit(-1);
	}
	if(!gladLoadWGL(hDC)){
		RLOG("Failed to load Wiggle API");
		exit(-1);
	}
	if ("GLAD_GL_VERSION_2_1") enhanced_mode=true;
	wglMakeCurrent(NULL, NULL);
}
/*...*/
}

instead of :

void MakeWGLContext(int depthBits, int stencilBits, int samples)
{
/*...*/
     if(pass == 0) {
	HGLRC hRC = wglCreateContext(hDC);
	wglMakeCurrent(hDC, s_openGLContext);
	glewInit();    
	if (glewIsSupported("GL_VERSION_2_1")) enhanced_mode=true;        
	
        wglMakeCurrent(NULL, NULL);
	}
/*...*/
}

I don't have made any change for X11 and GTK yet.

If you are interesse in change I can provide a patch file
