Something wrong with dmd's -c command?

$ dmd @dmd.rsp

OK, exe is built (win32). Now let's try compiling module-by-module via
-c and then linking:

make.bat:
@echo off

dmd -c -I.. -ofignore.obj ignored.d

All of these seem related to associative arrays.
If you demangle one of the symbols via std.demangle it becomes:

@property uint object.AssociativeArray!(immutable(char)[],
const(doxyparse.types.FuncTypedef)).AssociativeArray.length()

I can tell this is needed for the following symbol in my
'doxyparse.types' module:
struct Member
{
    FuncTypedef[string] funcTypedefs;
}

FuncTypedef is defined as:
struct FuncTypedef
{
    string ID;
    string name;
    string type;
    string[] parameters;
    string returnType;
}

There is nothing in the directory up from the current folder (-I..)
except the base folder of the project, so I don't think DMD is picking
up modules from unrelated directories.

I can't test with older versions of DMD because my project then ICEs.
I'd try with GDC, but apparently GDC has .length set as a ulong even
though I'm running x86, so I get  compilation errors there.

I'll have to reduce this to make a test-case.. but has anyone had
issues like these before?
