Linker errors after updating to DMD 2.060

[Danny Arends]

Hey all,

After switching to 2.060, I'm getting the following linker errors 
on a project of mine:

  Error 42: Symbol Undefined _D4core6memory2GC6extendFPvkkZk
build\unittest.obj(unittest)
  Error 42: Symbol Undefined 
_D4core6memory2GC6qallocFkkZS4core6memory8BlkInfo_

  Error 42: Symbol Undefined _D3std6loader14ExeModule_LoadFxAyaZPv
build\unittest.obj(unittest)
  Error 42: Symbol Undefined _D3std6loader12__ModuleInfoZ

Any idea's why it does compile but fails to link on:

  core.memory
  core.bitop
  std.loader

(by the way the 2.059 was able to link them just fine)
Code is available via github:
