No. There's a difference between DMD 2.070.0 and 2.071.0:
$ cat main.d
module main;
extern (C) int printf(in char*, ...);
extern (C) void main()
{
printf("asd\n");
}
$ dvm use 2.070.0
$ dmd --version
DMD64 D Compiler v2.070.0

$ dvm use 2.071.0
$ dmd --version
DMD64 D Compiler v2.071.0

$ dmd -betterC main.d
$ nm main | wc -l
2428
Note that "main" is declared as "extern (C)", which makes all the
difference.
