annotate dmd/attrib.c @ 737:041c1596d217
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.

Changed all '#if linux || __APPLE__' to '#if POSIX' so we can support other platforms too, thanx for the suggestion anders.
