Failed to compile xserver-xorg-video-ati from git

Hi! Compilation of xserver-xorg-video-ati from git show these problems:

../../src/radeon_kms.c: In function 'radeon_sync_scanout_pixmaps': ../../src/radeon_kms.c:481:2: warning: implicit declaration of function 'RegionDuplicate' [-Wimplicit- function-declaration] ../../src/radeon_kms.c:481:14: warning: assignment makes pointer from integer without a cast [enabled by default] Function `RegionDuplicate' implicitly converted to pointer at ../../src/radeon_kms.c:481 ../../src/radeon_kms.c: At top level: ../../src/radeon_kms.c:406:1: warning: 'transform_region' defined but not used [-Wunused-function]

Due to error 'Function `RegionDuplicate' implicitly converted to pointer' gcc refuse to accept it...
