Shells that support Posix and XSI extensions to Posix. Stuff like
${variable%%pattern}
${variable#pattern}
Hmm, they are required by Posix even; I wonder whether they used to be
extensions required by XSI only, or why else we would have chosen that
name. Anyway, that's what I mean.

I'm not sure what you're talking about: the configure part of Libtool
looks whether 'echo' doesn't interpret backslashes, and otherwise
searches for a (preferably builtin) command that prints without
expanding. And of course we also try printf, but it's known to be buggy
on some systems. It sets $ECHO to the preferred choice.
If you're experiencing a quoting bug, or a system where we choose a
non-builtin for $ECHO where a builtin would do the job just as well,
then please report a bug.
Also, some of the recommendations in the link you quote are rather
questionable. For example, the code in
<http://www.opensolaris.org/os/project/shell/shellstyle/#use_external_filters_only_for_large_datasets>
is much more portably (and likely faster, too) replaced by
case $x in *foo*) do_something;; esac
at the expense of using BREs over EREs, of course.
Also, some items explicitly recommend to use nonportable constructs over
portable ones, even without efficiency concerns. This is not a way to
go for Libtool.

Libtool patches go to [EMAIL PROTECTED] Note that nontrivial
patches require copyright assignment to the FSF.
