Remove the obsolete Winelib HOWTO and DDE status.

documentation/status/dde

-This is the status for DDE (i.e. raw dde messages) and ddeml.
-
-DDE was implemented by Micheal Veksler some time ago, it has been reported as broken
-by changes in the server and related parts of wine.  AFAIK no-one has tried to fix these
-and I have not tried to test them.
-
-ddeml was untouched until December 1998 when some of the Corel/Macadamian team started
-writing bits that were needed by Corel for the WordPerfect Suite port. These were mainly
-around string handling and have been identified in the change history for each routine.
-They were written to cope with a single instance only. About a week later I started 
-looking at ddeml as a whole.
-
-The initialisation was tackled first, then the routines produced by Corel/Macadamian
-were modified to cope with multiple instances of dde client/server and a first cut at
-the un-initialise routine. 
-
-DdeNameService has now been produced as a first-cut routine, but the monitor notification 
-must be tackled, followed by the main message reception routine and the invoking of the 
-callback. Serious testing from this point may well depend on Wine thread handling 
-settling down.
-
-The strategy so far has been to tackle the Unicode versions first. Once they have been
-accepted as close to complete then the 32-bit ASCII routines then the 16-bit routines.
-
-It is recognised that the solutions adopted may well not be suitable for wine-OS2, since
-that OS has its own DDE rotuines intermediate in integration between raw DDE and ddeml,
-also O/S 2 users may well want programs running under Wine to talk to native O/S 2 programs.
-I do not have knowledge of MacOS or the internals of BeOS, but these may suffer from the
-same problems.
-
-TO DO
-
-Complete initialisation, some of the 2nd call validation conditions have not been worked out
-yet and the code for enabling the message loop needs writing.
-
-Complete initialize and unitialize, also add the callback handling to DdeNameService.
-
-Add true Unicode handling to CreateStringHandle, QueryString, CmpStringHandles. Also find
-out why Initialize needs ASCII and Unicode variants.
-
-Add DdeGetLAstError and related handling in all other modules. Also find out what to do about
-storing errors that result in the instance failing to initialise in some way.
-
-
-Just about all the rest
-
-More specific items are commented in the code.
