Starting D with a project in mind.

[Andrew]

After roughly hacking all of the 'static assert "unimplemented"' 
lines in libphobos to just do whatever X86 does, I got it to 
build and install. Now I'm on 2063L and now hello world builds to 
8MB instead of 2MB (although it strips to 760k - twice the 
previous version).

So now I resume my quest to build vibe.d by first trying to build 
dub and I get :-

andrew at islay:~/dub$ ./build.sh
Generating version file...
Running gdmd...
/usr/local/gdc/include/d/4.8.2/armv7l-unknown-linux-gnueabihf/core/time.di:224:

/usr/local/gdc/include/d/4.8.2/std/net/curl.d:195: note: called

line 224 is trying to instantiate a Duration object. Any ideas ?
