so it is not Bourne-enough to count.
It's not by default; you just have to tell it explicitly to behave more
bourne-like.

Now that I've seen that, I think it is not Bourne-enough to count. :(
It tries to run awk with
the $errno_list argument instead of just passing output through to it.
Hopeless.
Huh? What it the precise error message?
Basically, the expansion of $errno_list was as if it were quoted, "$errno_list".
It only looked like it was being passed through to awk because the
multi-threaded
printing was much more intermingled than I normally see.
No way around it, zsh is just being gratuitously weird. If folks want to run
Bourne shell scripts with it, then they need to jigger it themselves.
ash:

Which version of ash? It works ok on my Debian box with dash 0.5.5.1 and
dash 0.5.2.
"dash" works fine. I have no idea which version of ash I have.
It won't tell me with any of --version --help -v or -V options.
So the version is whatever openSuSE currently ships with 11.4.
