  ##
  # Splits a command string such as ENV["MAKE"] into an argument list.
  #
  # On Windows, a value that names an existing file, such as
  # <tt>C:\path\nmake.exe</tt>, is taken as a single word because POSIX
  # shell splitting would consume the backslashes as escape characters.
  # Any other value is split like a POSIX shell command line, where a
  # path containing spaces must be quoted.
