Yes, for example:

   $ /bin/sh --version
   GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin12)

   $ /bin/sh -c 'echo -n hello'
   -n hello

   $ /bin/bash -c 'echo -n hello'

On a Linux machine with Bash 4, the "-n" does suppress newline,
even when invoked as /bin/sh, so not sure if it's a Bash 3 vs. 4
thing, or an OS X oddity.

For what it's worth, I'm using nix [1] to build s6, and it provides
an easy way to apply patches at build time, so it's not a big deal for
I'll leave it to you if you want to change it to 'printf' or leave it
as is.

Ah, thank you. I'm not actually using the shared libraries (building
and s6 with flag-allstatic), so I will try that route for skalibs.
