--- Comment #1 from Nicholas Wilson <iamthewilsonator at hotmail.com> ---
Is it enough to just  pass `-debug=mscrtlib` along with
`-mscrtlib=libcmtd/msvcrtd`?
the do 

version(Windows)
{
    debug(mscrtlib)
        enum = _ITERATOR_DEBUG_LEVEL = 2;
    else
        enum = _ITERATOR_DEBUG_LEVEL = 0;
}
this could be done automatically, of course but in the mean time the above
should work.
