Personally I think it's a good idea to *test* your software with Debug
Mode (or some other checked STL) as you would test with a memory
checker such as valgrind or purify, or a profiler, but it's not
something I would use for all non-release builds.

I still find it very surprising that Xcode defines those macros for
you, I would expect it to be something you have to ask for quite
explicitly.  Otherwise it is very difficult to debug any C++ program
that links to shared libraries, unless you recompile all those libs
(which is not a reasonable requirement.)
