  14 The problem, as far as I can tell, is that MacOS X has its getopt
  15 prototype in <unistd.h>, while I think other operating systems have it
  16 in other places. <unistd.h> is included by kpathsea.h, so you end up
  17 renaming both conflicting prototypes to YAKLUDGE.
  18
  19 I found a somewhat more elegant patch for this: Just #include
  20 <unistd.h> before defining YAKLUDGE.
