migrating to 64 bit

[Stephen Jones]

Thanks for your answers but I wasn't quite clear about what I 
asking. Basically I am on a 64 bit os but I want to continue 
compiling for a 32 bit os. I don't want to reconfigure Derelict 
because I already have all the functionality I need from 
Derelict. Until dmd on Windows 64 bit is sorted out, including a 
clear procedure for setting up the linker I have no need or wish 
to compile for 64 bit. Especially since any d program that 
compiles on 32 bit will compile under 64 bit.

Is there a flag on dmd that forces it to assume it is creating 32 
bit object files? Or is this not possible?
