Two question about this installer
1, where is the "exchndl.dll"? This dll is used to generate the crash callstack
2, I see the size of wxmsw28u_gcc_471tdm.dll is about 2.5M. The official wxmsw28u_gcc_cb.dll build with tdm gcc 452 is about 6.5M, why there the dll build from gcc 4.7.1 is much smaller? optimization of gcc 471?
