Building phobos with wine fails

[Andrei Alexandrescu via Digitalmars-d]

I've followed the instructions at 
https://wiki.dlang.org/Building_under_Posix to build posix on Win32 
using wine (awesome possum!). It works great for building dmd and then 
druntime. However when I try to build phobos I get the odd errors pasted 
below. Any ideas on why that is happening? Thanks! -- Andrei
