Most likely should be short_enums instead of arm*-*-* (I think the old arm non-eabi didn't use short enums) due to the fix r14-6517-gb7e4a4c626e applies when -fshort-enums is used. Also if you are adding a dg-bogus to the branch, it might makes sense to the same to the trunk (obviously without the xfail part). Also makes sense to add a reference to r14-6517-gb7e4a4c626e to the dg-bogus in the source too.

I don't know if this affects other targets than arm-none-eabi, so I used arm-*-*. If you think it should be *-*-* or some other target selector, please let me know what to use instead.
