Removed warnings on ignored aligns. Only do aligment on packed structs, align(1) struct Packed { ... } Changed the way struct/class fields are added, first small part of cleaning up these... Make struct/class/union fields aware of any anonymous struct/union they might be part of, not yet really useful, but part of getting better union support.

1) Do a checkout of tango trunk in the ldc root dir (along dmd, gen, runtime etc).

    *    svn co http://svn.dsource.org/projects/tango/trunk ../tango

2) Patch the runtime

    *    sh patch-tango.sh

3) Compile the runtime

    *    sh build.sh
