MSys provides a Windows version of GNU make which uses MSys' bash port.

Using cmd.exe fails if you need to use the same makefiles on both
Unix and Windows and the makefiles aren't trivial.

Yes; nmake "understands" quoting.

With a Unix make, quoting only works insofar as the quotes are treated
verbatim, so they will still be present when the variable is expanded in
the context of a shell command. The quotes don't have any significance to
make itself, so you can't have a list of quoted filenames. E.g. if you
have:

	FILE1 = "hello foo"
	FILE2 = "goodbye bar"

	default: $(FILE1) $(FILE2)

"make default" will attempt to build the targets:

	"hello
	foo"
	"goodbye
	bar"

So you can use quoted strings in commands, but not as prerequisites or
targets. And e.g. $(wildcard ...) won't add any quoting to the results.
