   Counterexample:   
   https://github.com/freebsd/freebsd-src/blob/main/contrib/one-true-awk/awk.h   
      
   The copyright notice says 'Lucent' but that's an AT&T spinoff,   
   presumably the one that ended up owning that version of awk when they   
   did the split.   
      
   It’s not a recent addition, either. The version in 4.4BSDLite2,   
   https://github.com/sergev/4.4BSD-Lite2/blob/master/usr/src/contr   
   b/awk.research/awk.h,   
   has an explicit AT&T copyright.   
      
   Compare   
   with https://github.com/calmsacibis995/svr4-src/blob/main/cmd/awk/awk.h,   
   the same file in SVR4, and the relationship is obvious.
