D and SCons

[Sean Kelly]

From an ABI perspective, I know GDC used to not pass the first function argument in EAX on x32 (ie. the calling convention for extern (C) and extern (D) were identical).  I imagine this is still true, but one of the GDC folks would have to say for sure.  The goal however is certainly to make the ABI sufficiently detailed that what you're saying would work.
