There were many examples "readability is better" for ancient ports.

In most cases, geeks who knows the machines are not familiar
with NetBSD, and NetBSD geeks don't know the hardware behaivor.

Note sys/arch/atari/stand/installboot is not cross ready and just
a native binary (it's in my TODO list to add atari support into
MI installboot though).  Fortunately installer floppy doesn't require
installboot. (bootstrap kernels are loaded by loadbsd.ttp for Atari TOS)

pkgsrc/emulators/aranym can boot FALCON kernel and show boot messages
but it doesn't implement MFP timer required to run NetBSD/atari..

Anyway, it looks even with gcc45 sed(1) in atari's sysinst.fs dumps core.

You can test it on tme by copying crunched "/usr/bin/sed" binary
from netbsd-7 atari's sysinst.fs.gz:
ftp://nyftp.netbsd.org/pub/NetBSD-daily/netbsd-7/201411140020Z/atari/installation/miniroot/sysinst.fs.gz

"./sed y/0123456789/abcdefghij/" dumps core even on TME sun3
(though the installer worked on NetBSD/atari 6.0 days).
Some libc changes trigger it?
