It can be found at: http://sourceforge.net/projects/mingw/files/GCC%20Version%204/Current%20Release_%20gcc-4.4.0/gcc-full-4.4.0-mingw32-bin-2.tar.lzma/download The release notes of it states that it uses dwarf2 exceptions only and currently can not use sjlj exceptions. "- Zero cost exceptions: New exception model Dwarf only has performance penalty when being thrown. The old model, SJLJ, is no longer available." Which can be found in this document: http://sourceforge.net/projects/mingw/files/GCC%20Version%204/Current%20Release_%20gcc-4.4.0/gcc-4.4.0-mingw32-notes.txt/download Regards Ingrater
