extern(C) and extern(D) are both documented to be the same as the 
platform's C calling convention everywhere except x86 windows:

There have been times when differences were noted (I recall a 
particularly bad one related to passing structs by value on 
64-bit linux) and there may be more. When they are, they should 
be reported in Bugzilla.
