I have some and use them in some code, they represent ISA 2.06 MAVN=1 (version 2) Can I keep them? if so, should I put them somewhere useful to others? Examples: union mas1 { u32 _val; struct { u32 v:1; u32 iprot:1; u32 tid:14; u32 _reserved_1:2; u32 ind:1; u32 ts:1; u32 tsize:4; u32 _reserved_2:8; }; }; -jx
