Thank you Sean !

leaves a lot of room for improvements, f.i.:

BOOL DllMain(HINSTANCE hInstance, ULONG ulReason, LPVOID pvReserved)
{
     switch (ulReason)
     {
	case DLL_PROCESS_ATTACH:
	    gc_init();			// initialize GC
............
	case DLL_PROCESS_DETACH:
............
Pretty sure it will make you shake your head - But I have to ask: Shall 
I simply replace gc_init() with rt_init().

I am sorry about beeing so uninformed:ignorant but I never really 
understand the GC/Runtime Tango/Phobos problem.

So Sean;  I remain with a Thank You and hope you will be patient enough 
to offer a minimalistic sample ?
(probabely on DSource/Tango. may be more people are interested)
