Problem Building Phobos

[Meta]

DMD and D Runtime build fine, but when I try to build Phobos, I 
get this error:

phobos.lib: Error: multiple definition of ti_Ag: 
_D12TypeInfo_Axa6__initZ and object_: _D12TypeInfo_Axa6_initZ.

If I'm understanding what it's telling me, the modules ti_Ag and 
object_ are both defining that symbol, causing the conflict. 
While there is a TypeInfo_Axa in ti_Ag, there isn't in object_, 
so I have no idea what's going on here.
