Are these all your patches to druntime?  For example, you
mentioned earlier that you "had to rewrite the complete core.stdc
bindings," but there are only three small patches to core.stdc in
the above branch:

https://github.com/jpf91/GDC/commit/d807f9d8a1cc51efe8b14a48d6a294174dc92168

You also mentioned porting the GC, but there are no patches for
that.  I thought you'd gotten further along on an Android port
based on your earlier comments.  It appears that we hit the same
stderr issues though. :)
