I'm not familiar with the internals of compiler and runtime 
architecture, but I'm curious, why is is that so many complicated 
patches are necessary?
I understand the D runtime has to access Windows API, correct? But that 
should all be available in the MinGW target as well, no? Otherwise, what 
is the difference here when DMD for Windows is compiled, vs when GDC is 
compiled?
