Xorg server compilation error

[h3140067568]

I am a Linux developer from China. I encountered an error while compiling 
xorg-1.12.2 version of the development project. The error comes from the 
sdksyms. c file in xfree86 under the hw file in the project, which prompts 
sdksyms. c: 324:15: error: expected expression before ',' token
(void *) &,                                                  /* ../../ 
include/os.h:93 */
