Reproduction case

Compiling the following three files using `dmd -c a.d` causes the compiler to
fail compiling code in std.complex:

a.d
---
import b;
interface A {}
---

b.d
---
import c;
import std.datetime;
interface B : A {}
---

c.d
---
import a;
interface C : A {}
---

output:
---
C:\D\dmd2\windows\bin\..\..\src\phobos\std\complex.d(678): Error: struct
std.complex.Complex does not match any template declaration
C:\D\dmd2\windows\bin\..\..\src\phobos\std\complex.d(678): Error:
Complex!(real) is used as a type
[...]
---

The error occurs for different configurations of imports and triggers errors in
completely different locations. Does not occur using DMD 2.060.
