  * undef XDestroyImage instead of defining XUTIL_DEFINE_FUNCTIONS
  
  Comment in the file:
  Xutil.h overrides some functions with macros.
  In recent versions of X this can be turned off with
  
      #define XUTIL_DEFINE_FUNCTIONS
  
  before the #include, but this doesn't work with older versions.
  As a workaround, we undef the macros here.  Note that this is only
  safe for functions with return type int.
  

    M ./include/HsXlib.h -1 +12
