GNU make

From RFID Guardian

All software assumes that you have GNU make on your system. Chances are that that's the case already. If you run Linux, CoLinux or Cygwin, the default make is GNU make. On many other systems, GNU make is installed as gmake. Then you should replace calls to 'make' below with calls to 'gmake'. If GNU make is not installed, you will need to download it from the GNU make pages, and install it yourself.
