Synchronize source tree with OpenBSD

note: due to recent changes in the codebase of OpenBSD,
out libcom_err will be incompatible with theirs...
but this is no issue because we don't provide a dynamically
linked one, and theirs won't be provided longer any more anyways.

 	aclocal.m4
-		This is covered by the GNU General Public Licence (GPL)
-		as it contains modified versions of macros that come with
-		GNU autoconf.  As this is used solely for configuration,
-		the pdksh code itself is not covered by the GPL.
-		The following is taken from autoconf 2.x documentation
-		(info autoconf questions distributing) concerning use
-		of autoconf in programs:
-
-		   There are no restrictions on how the configuration
-		   scripts that Autoconf produces may be distributed
-		   or used.  In Autoconf version 1, they were covered by
-		   the GNU General Public License.  We still encourage
-		   software authors to distribute their work under terms
-		   like those of the GPL, but doing so is not required
-		   to use Autoconf.

 That's it.  Short and simple.
