Mariano, can you please change the instructions to avoid further confusion. To install mingw+msys using single, painless step, one should download latest installer from here: http://sourceforge.net/projects/mingw/files/Automated%20MinGW%20Installer/mingw-get-inst/ Today, the mingw-get-inst-20110530 is latest one. -- Best regards, Igor Stasenko AKA sig.
