D's makefiles...

[Atila Neves via Digitalmars-d]

I did a `git up` on dmd, druntime and phobos, but phobos wouldn't 
build. Weird, but I had to fork phobos anyway, let me do that. 
Still wouldn't build. I tried `make clean`, can't remember 
exactly what happened but that didn't work either.

In the end I `rm -rf`ed dmd and druntime, recloned them, rebuilt 
them and _then_ phobos could build.

Feels like when I wrote Makefiles by hand, I'd forgotten it could 
get this bad.
