----------------
module stru;

struct StruB
{
        bool flag;
        int[] nums;

        bool opEquals(bool b) { return flag == b; }
}

struct StruA
{
        int num;
        StruB sb;
}
----------------
module main;
import stru;

StruA[] arr;

void main()
{
    StruA s;
    arr ~= s;
}
-----------------
dmd -c stru.d
dmd -c main.d
dmd main.o stru.o

main.o:(.data._D21TypeInfo_S4stru5StruA6__initZ+0x1c): undefined reference to
`_D4stru5StruA11__xopEqualsFKxS4stru5StruAKxS4stru5StruAZb'
collect2: ld returned 1 exit status
--- errorlevel 1

DMD32 D Compiler v2.064-devel-e5a0c64 Linux
This is a regression against earlier 2.064 or 2.063.2

Adding opEquals to StruA or a single command compilation both solves the
problem, so feel free to downgrade.
