extern(C) does not have any effect on parameters.  Note that you can easily
implement extern(C) functions in D (in fact the runtime heavily relies on
this).  AFAICT, it basically is just a way to treat the symbol as demangled.

Also note that because C treats fixed-sized array parameters as pointers, and D
treats them as values, the following idiom has emerged, which would not be
possible if ref wasn't allowed:

extern(C) int pipe(ref int[2] fds);

Changing to websites, since this is really a spec issue.  The compiler is
implemented properly IMO.
