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".
