# This trick is originally from BearSSL to distinguish between bmake/nmake
# ======================================================================
# 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/nmake.mk", whereas
# GNU/BSD make will include "mk/bmake.mk".
