Maybe it has something to do with that extra "const" ? What is that ?
(looks to me like it is trying to use the keyword like it was in C++)

Although when I tried it, it still worked OK even with the "const"...

struct __CFString { } // opaque
typedef const __CFString* CFStringRef;

extern(C) CFStringRef __CFStringMakeConstantString(char *cStr);
alias __CFStringMakeConstantString CFSTR; // only for string literals


Then using it something like:

     err = CreateNibReference(CFSTR("main"), &nibRef);
     if (err != noErr) goto CantGetNibRef;

So I'm not sure what else your code is doing differently than mine ?
