1. Download the latest MinGW automated Installer from:
http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get-inst/
2. Run it, select Download latest repository catalogues, then select all components to be installed (you need C and C++ compilers, if you want you can leave out the other three - Fortran, ObjC, Ada)
3. Once MinGW is installed download the autotooled mpatrol version (we have it thanks to Vincent Torri) either from the SVN repository via an SVN client:
