I was trying to rebuilt Mesa from Git (31-Dec-2015).

There were two errors.

1. The following file 

#include "...nouveau.h"

was missing in both

- src/gallium/drivers/nouveau/nouveau_screen.c

- src/mesa/drivers/dri/nouveau/nouveau_screen.c

Compiler complained that 'nouveau_drm_new', 'nouveau_device_new', 'nouveau_destroy_screen' were functions implicitly declared

So I had (Sorry I am not a programer :( )

#include "/usr/include/libdrm/nouveau/nouveau.h"

To fix the problem. And it was OK.

2. The second issue is for the commit provided on 22-Dec-2015
