Thanks. I installed the patch enclosed below.

The workaround in this case is easy. Just omit the outer quotes and
remove the inner backslashes:
output_verbose_link_cmd=`$echo "X$output_verbose_link_cmd" | $Xsed -e "$no_glob_subst"`
The outer quotes aren't needed. This issue is discussed in the
Autoconf manual's Shellology section.
Anyway, here's the Autoconf patch I installed.

* lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
with pdksh, too. Problem reported by Patrick Welche via
Gary V. Vaughan.
* doc/autoconf.texi (Shellology): Note that set -o posix is
useful for pkdsh, too.
