[ About the 8-bit bug on Ultrix ]

   Finally, I'd like to understand how this turns out to be a malign bug.
   I mean, I do see the 8th bits are set while they should not, but if
   such a bug could have leaved inside a shell, it probably means that
   the shell itself doesn't care about the 8th bit, doesn't it?

   So where did it *hurt*, where did that 8th bit set made a difference?
   What wrong behavior appeared?

When the Ultrix /bin/sh reads the config.cache file, it does discard
the 8th bit.  So this bug almost certainly does not hurt, provided you
always read config.cache with the same shell, and provided you don't
accidentally look at it manually.
