   9 # knowledge on how the X11 include files are formatted. It will
  10 # probably need to be modified for new include files. It also fails
  11 # for certain prototypes (notably those with function pointer
  12 # arguments or results), so these must be added manually. And it
  13 # relies on a fixed location of X11 includes (/usr/X11R6/include/).
