When was this as I'm building 6.1.5 it could actually predate that fix. However I don't see anything like that in CVS after 6.1.5.
I can't find the information right now, but if I remember right, I wrote a fix that avoided the problem in libc, but someone else argued that this was really a bug with awk, and went on to fix it there instead. (And I hope I'm not misremembering, and that it was groff, but I think it was awk. The groff problems where that groff itself could not be compiled natively).
But I can't remember exactly when we dealt with it. :-/ But your further digging here suggest that it's not related anyway... Johnny
