I\'ve gone to http://sourceforge.net/project/showfiles.php?group_id=2435, downloaded the Automated MinGW Installer for MinGW 5.1.4 and at the same time the GNU Source-Level
The TDM GCC/MinGW32 builds installer includes gdb. It's gcc 4.4.x with all the core binary packages required for basic Windows development, and is widely used without any unusual problems.
