strdup(), strcasecmp(), strncasecmp().  Should test to see
if these are truely needed.  Hopefully their addition will
not break other platforms.

Sync portable.h.nt with portable.h.in

Add ac/bytes.h to provided sized types.
Use new sized type in md5/sha1 header through simple typedef.
Should substitute old type for new everywhere.

not to require knowledge of byte order such that this check can be removed.

Update NT port.

  This could cause problems on odd systems.  The generic
  headers should be extended as needed to include necessary
  system headers or, if necessary, make explicit declarations.
Extended ac/string.h header to look for string.h/strings.h if
  STDC_HEADERS is not defined.  Also provide basic declarations for
  str*() functions.  This could cause problems on odd systems.
Extended ac/unistd.h header to define basic declaration for misc
  functions that might be missing from headers.   This includes
  externs for getenv(), getopt(), mktemp(), tempname().
Protect fax500.h from multiple inclusion.  Moved includes of
  system/generic headers back to source files.
Made mail500 helper functions static.
Fixed includes of ctype.h, signal.h, etc. to use generics.
lutil/tempname.c: was including stdlib.h twice, one should stdio.h.
Wrapped <sys/resource.h> with HAVE_SYS_RESOURCE_H.
lber/io.c/ber_get_next(): Changed noctets back to signed.
  Used with BerRead which expects signed int as second arg and
  returns signed int.

Most function and variable definitions are now preceded by its extern
definition, for error checking.  Retyped a number of functions, usually
to return void.  Fixed a number of printf format errors.

API changes (in ldap/include):
  Added avl_dup_ok, avl_prefixapply, removed ber_fatten (probably typo
  for ber_flatten), retyped ldap_sort_strcasecmp, grew lutil.h.

A number of `extern' declarations are left (some added by protoize), to
be cleaned away later.  Mostly strdup(), strcasecmp(), mktemp(), optind,
optarg, errno.

	configure checks for getpwuid(), sys/resource.h, and pwd.h
	Fix !TERMIOS && !SGTTY ifdef in ud/util.c

Update NT portable.h and features.h

to force no prototypes or require them.
Remove _WIN32 clause.  Will update portable.h.nt to define __NEED_PROTOTYPES.

 #include <stdlib.h>    to get malloc & co various places,
 #include <ac/string.h> to get strlen & co in (liblutil/setproctitle.c),
 declare ch_malloc & co (slurp.h), avl_find_lin (avl.h), Malloc (ud/edit.c).
Also changed ch_malloc & co from char* to void* functions.

-thread & -pthread are still treated as libraries, will need
additional work to use them as CFLAGS.
Eliminated HAVE_DCE define (was redundant) and its use.  Code
now relies on draft4 and function existance tests.

Modified clients to reduce use of ldapconfig.h.edit.
ldap_{get,set}_option support is relatively complete.  Needs
to be extended to support other "features" of OpenLDAP.

  ifndef HAVE_PTHREAD_KILL pthread_kill() code and prototype.
  Fix HAVE_FUNC_PTHREAD defines from previous change.

Fix pthread_attr_init/destroy pthread draft4 compatibility.

  configure generates ldap_features.h based from ldap_features.h.in
  LDAP_REFERRALS -> LDAP_API_FEATURE_OPENLDAP_V2_REFERRALS
  LDAP_DNS -> LDAP_API_FEATURE_OPENLDAP_V2_DNS

Updated portable.h.nt based upon portable.h.in (1.11).

Remove AC_GCC_TRADITIONAL check.  Likely to cause more harm than good.

Added ac/stdarg.h and updated liblber encode/decode to use it.
