  25 # The lines below are a horrible hack that nonetheless works. On a
  26 # "make" utility compatible with Single Unix v4 (this includes GNU and
  27 # BSD make), the '\' at the end of a command line counts as an escape
  28 # for the newline character, so the next line is still a comment.
  29 # However, Microsoft's nmake.exe (that comes with Visual Studio) does
  30 # not interpret the final '\' that way in a comment. The end result is
  31 # that when using nmake.exe, this will include "mk/Win.mk", whereas
  32 # GNU/BSD make will include "mk/Unix.mk".
