[dmd-internals] Nearly all builds broken

[Jonathan M Davis]

As of right now, all of the builds except for the Posix dmd builds are 
failing. So, it looks like the UTF-related changes broke everything, and the 
commit to posik.mak which followed those fixed the dmd build on Posix, but that 
still leaves everything else. On 64-bit Linux, the druntime build is spitting 
out this:
