I've been revisiting this today, and I hit a problem during testing that 
might be related.  It seems the awk on NetBSD behaves differently when 
reading from stdin, at least compared to other OS that I have handy that 
also ship one-true-awk.

Simple reproducible testcase:

  $ uname -rsm
  NetBSD 10.0 amd64
  $ awk --version
  awk version 20200218
  $ echo foo | awk 'BEGIN { while(getline < "-") }'; echo $?
  2

  $ uname -rsm
  Darwin 23.5.0 arm64
  $ awk --version
  awk version 20200816
  $ echo foo | awk 'BEGIN { while(getline < "-") }'; echo $?
  0

  $ uname -rsv
  SunOS 5.11 joyent_20210826T002459Z
  $ awk --version
  awk version Aug 27, 2018
  $ echo foo | awk 'BEGIN { while(getline < "-") }'; echo $?
  0
  $ nawk --version
  awk version 20121220
  $ echo foo | nawk 'BEGIN { while(getline < "-") }'; echo $?
  0

Unfortunately this breaks the behaviour of the "distinfo" target when 
nothing has changed.  Annoyingly you can't even override it:

  $ echo foo | awk 'BEGIN { while(getline < "-"); print "hi"; exit 0; }'; echo $?
  hi
  2

I don't really know what to do about this, unless there's some esoteric 
workaround ... which I just found while writing this!  If you specify 
"/dev/stdin" instead then it does work.  I'll send this anyway as I feel 
it's a bug that should be fixed, and it probably explains the behaviour 
difference you were seeing compared to me.
