Error by building druntime

[Namespace]

Hey, me again.
I cloned dmd from git head and try to build it with: make 
-fwin32.mak release
But I get these errors:

dmc -c -Ibackend;tk  -DMARS -cpp -D -g -DUNITTEST -e -wx 
-DDM_TARGET_CPU_X86=1 -

I see them for the first time, so can someone explain me what is 
going on there? o.O
