 The code in X11/xlib.h is:

 {{{

   415   /*
   416    * Data structure used by color operations
   417    */
   418   typedef struct {
   419           unsigned long pixel;
   420           unsigned short red, green, blue;
   421           char flags;  /* do_red, do_green, do_blue */
   422           char pad;
   423   } XColor;
 }}}

 being expanded to:

 {{{

 typedef struct {
  unsigned long __attribute__((altivec(pixel__))) unsigned short;
  unsigned short red, green, blue;
  char flags;
  char pad;
 } XColor;
 }}}

 The reason for this is this built-in rule:

 {{{
 #define _ARCH_PPC 1
 #define _ARCH_PPCGR 1
 #define __ALTIVEC__ 1
 #define __VEC__ 10206
 #define __vector __attribute__((altivec(vector__)))
 #define __pixel __attribute__((altivec(pixel__))) unsigned short
 #define __bool __attribute__((altivec(bool__))) unsigned
 }}}

 Isn't it pretty silly to assume that a pixel will always have 16 bit?
 These 16 bit would be OK for each colour component and the alpha channel
 for transparency…
