enables if MINGW32 and always enables if MINGW32).

Update single debug/release not to use service manager nor event manager.
Likely breaks MINGW32 port.

(excepting WIN32_LEAN_AND_MEAN).  Rework openlog/closelog use to
eliminate need for defines.

ifdefs to depend on _WINNT, which is bogus. Added _WIN32 back on these ifs,
and fixed some other include problems.

as s_addr member of in_addr may be a bitfield.

avoid having to define macros by hand in acconfig.h (which
were mistaken added to portable.h.in).

See README 1.27 log

  Remove macros already in Windows headers: strdup, FD_SETSIZE
  Set HAVE_SNPRINTF and HAVE_MEMORY_H to reflect NT environment
  Moved LDAP_DIRSEP macro to ldap_config.h.in
  Moved LDAP_SIGUSR macros to ac/signal.h

sources of entropy.  Should be extended to support a reasonable fallback.

avoid clashes with Kth Kerberos.

schemes are supported.  This should facilate server rootDSE
advertisement of supported schemes, etc..

Old code applied sync flags to store(), however supported DBMs
require such flags to be specified during open().  The new
code now applies flags in ldbm_cache_open (which calls ldbm_open).
ldbm_cache_close() now calls ldbm_sync().  This will force
a updating of on-disk contents after each LDAP operation.
The old code either failed to sync the on-disk contents until
close or synced on every store.   Per LDBM operation syncing
*should* be safe enough... real data safety requires transactions.
Removed nosync option from BDB2 as it is not compatible with
txn support.
Also added code to disable DBM level locking as slapd is only
process acessing the databases (dbnolocking).

* all others: Added DESTDIR support

If not available, LDBM uses big mutex and BDB2 is disabled.
Should add BerkeleyDB version detection...
