554	# Note: OS_TARGET should be specified on the command line for gmake.
555	# When OS_TARGET=WIN95 is specified, then a Windows 95 target is built.
556	# The difference between the Win95 target and the WinNT target is that
557	# the WinNT target uses Windows NT specific features not available
558	# in Windows 95. The Win95 target will run on Windows NT, but (supposedly)
559	# at lesser performance (the Win95 target uses threads; the WinNT target
560	# uses fibers).
561	#
562	# When OS_TARGET=WIN16 is specified, then a Windows 3.11 (16bit) target
563	# is built. See: win16_3.11.mk for lots more about the Win16 target.
564	#
565	# If OS_TARGET is not specified, it defaults to $(OS_ARCH), i.e., no
566	# cross-compilation.
567	#
568
569	#
570	# The following hack allows one to build on a WIN95 machine (as if
571	# s/he were cross-compiling on a WINNT host for a WIN95 target).
572	# It also accomodates for MKS's uname.exe. If you never intend
