This one is unnecessary.

UNW_FLAG_MASK
UNW_FLAG_OSMASK
UNW_VER

These are all defined for completeness. An unwind header has 6 fields, and we define macros for extracting all of them, even though currently we only use 3 of the macros. If we delete these, then we lose useful info, the size and position and name of the 3 currently unused fields. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
