The warning is only activated by +w, which is turned on for adlc but not for the rest of the hotspot build. Based on this, I have revised my proposal to just disabling this warning for adlc and the particular compiler version.

I think the new approach is good, e.g. disable the specific warning.
However, only doing so for this one compiler rev (I assume 513
corresponds to SS12u4?) seems like a mistake to me. I don't expect the
warning to go away with future compiler versions.
