Well, as John hints, that doesn't work for MinGW.  It has both STABS and DWARF-2 support and defaults to STABS.  And MinGW seems to be the port of choice ATM.

I guess the wizard could do a preflight to be more wizardly... e.g., if you run "gcc -v" you can find:

$ /C/mingw/bin/gcc -v
Reading specs from C:/mingw/bin/../lib/gcc/mingw32/3.4.5/specs
...

and then reading this file, find:

*asm_debug:
%{gdwarf-2*:--gdwarf2}%{!gdwarf-2*:%{g*:--gstabs}}

And deduce that the default is stabs (and/or search for "gdwarf.*" and pick that...)
