Initial revision
these files were only to be added in vendor branch
these files don't belong into mirbsdksh, either
the last sync with OpenBSD seems to have introduced more manpage errors
we don't have alpha, and stuff like that belongs
into conf-end.h anyways (autoconf annoys)
Improvements from the "ksh_maintainer" tag (development branch):
- use game-of-life
- add configure script (public domain, thus: miros licence)
  to make it portable
note that public domain does not exist where this OS comes from
(doesn't change much, though)
add (c) and "fix" build on GNU systems (tested)
add MirOS to version
This is mirbsdksh-1.2, passing all expected (all but three) tests
on MirOS BSD-current, and failing like 37 on Walgrind GNU/Linux
(probably some of these are environment-dependant):

better generation of config.h.in (if needed)
please note this is still only used by BuildGNU.sh, not by
the MirOS build process
d'oh; when specifying CPPFLAGS, gcc should use them.
while here, restructure the file.

With these changes, mirbsdksh-1.2 passes all expectations and tests
on Walgrind GNU/Linux (-current version); thanks to cnuke@ (Josef
"Jupp" Söntgen) to having me a test account to validate this.
in case someone wants to build a more small, posixlike sh...
* more sections to strip
* manpage fixes

tested on SuSE GNU today.
man page fixes
whoops. even better.
another fix round
sync with ksh.1tbl
sh.1tbl is now derived from it
build process improvements
builds with -Werror -Wall and without -Wno-unused now
GNU now uses improvements and mkstemp, too
correct version variable for sh(1)
pull in ksh_maintainer branch: mkstemp() checks
mkstemp check is there, use it
