There are still problems with packed enums. John Cooper's example program
compiles on g++ 4.3.2, but testEnum2 is still not packed. More details in Bug
#39219.

I'm afraid it will take a while for this feature to be added. It is in fact an 
enhancement request. Also, even if a patch was made today, it would not be 
eligible for 3.4.x anymore, so it would go into 3.5.x, which won't see the 
light until 2005.

Of course, if you can use a custom compiler version, you could backport such a 
patch to a local 3.4-based compiler. If you really need it done fast, I'm sure 
you can find a contractor that can develop it quite fast. I suggest you to ask 
on the gcc mailing list about it.

Thanks Andrew for confirming.

I see you've reclassified it as an enhancement.  That being the case, can I 
expect it to be fixed in the near term??  

If not, do you have any suggestions for a workaround?  The reason we can't use 
-fshort-enums is it's a large complex system with interfaces into other systems.
..  using -fshort-enums invariably leads to incosistencies and segfaults :(

Thanks again,
-John

Well this is no longer rejected on 3.4.0 but it still ignores the attribute for some reason.  I think the 
documention was written for the C front-end but never updated for the C++ front-end at all.
