>Description:
	During the final processes of release engineering NetBSD 1.6,
	I observed that the text.tgz set didn't contain the same
	contents on some MACHINE_ARCHs (whilst it did on others).

	One of the problematic MACHINE_ARCHs is m68k.
	I noticed that "C++ groff" applications differed.
	I was able to find 3 different groups of files which contained
	the same contents:
		a) amiga atari hp300 mac68k x68k
		b) luna68k mvme68k news68k next68k
		c) sun3

	I.e, any MACHINEs in a given group had the exact contents, but
	each group had different contents.

	An example, comparing amiga, atari, and luna68k:

    ---8<---
	extract /ftp/pub/NetBSD/NetBSD-1.6/amiga/binary/sets/text.tgz

	compare /ftp/pub/NetBSD/NetBSD-1.6/atari/binary/sets/text.tgz

	compare /ftp/pub/NetBSD/NetBSD-1.6/luna68k/binary/sets/text.tgz 
	Files amiga/usr/bin/addftinfo and luna68k/usr/bin/addftinfo differ

	Notice that  (amiga == atari ) != luna68k 

	sun3 is a weird case:

	(The comparisons are made with a hokey script which extracts the
	various sets into temporary directories and runs "diff -qr ...")


>How-To-Repeat:
	Notice that amiga/binary/sets/text.tgz does not contain the
	same binary contents as luna68/binary/sets/text.tgz.


>Fix:
	... is left for m68k toolchain gurus?
