        } while(value > 0);

        SendMessage(p, (buffer.ptr + 31) - p);
     }

     static nothrow pure void Write(A...)(A a)
     {
        foreach(t; a)
        {
            Write(t);

     static nothrow pure void WriteLine(A...)(A a)

GDC doesn't catch the ambiguity between...
   static nothrow pure void Write(A...)(A a)
     and
   static nothrow pure void Write(in string text)
... but LDC does.

Who's right?

LDC
the LLVM D compiler (0.12.1):
  based on DMD v2.063.2 and LLVM 3.3

GDC
arm-none-eabi-gdc (GCC) 4.8.2
Copyright (C) 2013 Free Software Foundation, Inc.

Also, is there a way to know which version of DMD GDC is based on?
