I remember I did remove object dir and old tools (from TOOLDIR and DESTDIR), which were from 

NetBSD amelia2 9.99.82 NetBSD 9.99.82 (NetBSD-HEAD amd64.nb999-20210601) #0: Tue Jun  1 21:21:00 GMT 2021  root@amelia2:/usr/obj/usr/src/sys/arch/amd64/compile/SANDY7 amd64

I have never used -E with, heeding the advice on the hazards that would entail.

Where the error showed toward the end of the build log,

I just did what you suggested, it seemed to build and install, I will have to try again after running "cvs up -dP -A" in src and xsrc directories.

Thanks for your help; I don't know if this will give me a successful build until I try it, hopefully this upcoming weekend.
