Solution:
pragma(lib, "D:\\D\\dmd2\\windows\\lib\\phobos.lib");

I have to link the phobos lib by myself. o.O

pragma(lib, "D:\\D\\dmd2\\windows\\lib\\phobos.lib");

Might help. Please try to define this somewhere in your code - specifying the library in the project might also be sufficient.

Why is the phobos lib automatically detected with dmd 2.062 , but not with 2.063?

I dunno, I suspected the sc.ini to be modified in some way, but surprisingly nothing changed in there. Anyway I just built a trivial sample program w/o explicitly linking in phobos successfully - dunno the reason why it's not working in other cases.

Any other answer? I have the same problem again.
And I hate it.
