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