Why ld not read some non-virtual thunk in a import library or dll?

And I have another question here. Could you please tell me why the
corresponding DLL provide both "@xx" and "no @xx" symbols, but the
libxpcom_core.dll.a just provide the ones without "@xx"? And, when I
use ld to link to the DLL directly instead of the import library, it
failed, too. Could you please tell me why it failed again?
