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".
