First: it's a bug in pdksh that `set -o posix' causes the shell to
misinterpret "...`...\"...\"...`..."

Don't believe the comments in the source code of pdksh.  The authors
have misunderstood POSIX in this respect.

And yes, in general "set -o posix" is beneficial for configure scripts.
And no, not all shells except zsh get this setting with Autoconf 2.60.
There are many more shells out there than those that exist on GNU/Linux.

Exactly.  The code you cite is from an old version of Libtool.  1.5.22
does not contain it, and as far as I know, should not have this problem.
If you can find otherwise, please report to bug-libtool, we'll be happy
to fix it then.
