Yes, but the problem is not to access command line arguments, but to run 
code before the GC initialization i.e. before _d_run_main is executed.

If we can assume a C++ backend, using static initialization of a C++ 
global could work:

    static bool initGC = configureGC();

because the C++ runtime runs configureGC before calling C main. I'd 
rather like to see a solution using D, though.
