>>553 As a general rule, you should choose the default SJLJ packages, unless you know you need faster exception handling and can guarantee you'll never need to unwind through non-DW2-compiled stack frames (such as a Windows callback). If you chose the DW2 packages, consider removing the "-dw2" suffix from the program names. See README-gcc-tdm.txt, included in the core package, for further notes on this topic.
