The GNUmakefile.am was trying to use .mid files in distribution,
which has now been removed.

        Second attempt at GNUMakefile.am

	Ensure GNUMakefile.am includes new ditsputact.c routine.

	Fix commenting problems in ditsputact.c

	Fix compiler warning in ticker.c

	Change approach to disabling warning about fall through in case in
	   duitoken.c, use the comment approach rather then the pragma.

	Changes needed to ctest.c to ensure the output is always consistent
        regardles sof machine performance.

       Fix issue in sdptest.C and don't output result which changes
       on different machines.

        Some of the testing diff commands don't work reliably due to
        things comming out in different orders.  Disabled for the
        moment.  Also the sdptest does not give the same results on
        32 bit and 64 bit machines which is not being handled
        correctly yet.

        LISTACTALL was listing overriden versions of actions, resolve that.

	Add DitsIsRegTestMode() function, which returns true if the
	    DRAMA_REG_TEST envrionment variable is defined.  This allows
	    us to change the output of programs when running in regression
	    test mode (e.g. don't output as much floating point precision).

	dmakefile reworked to capture output of tests and run tests during
	normal build.

	Add DitsPutAction() routine - simplier way of adding one action.

	Add support for action descriptions - via DitsPutActions(), new
	    DitsPutAction() routine, DitsGetActDescr() routine and
	    output by control messages.  Add DitsPutActDescr() and
	    DitsPutThisActDescr() routines.

	Fix various warnings from gcc 8.3.  Included some string length
	issues but only in test program, but most were about switch statement
	fallthroughs (a comment is now required to this is delibrate, to
	turn off the warning) and "const" returns which were unecessarry.

	If ditscmd is built with the DUL_BUILD macro defined, then it
	invokes DulLoadFacs().  The idea is that whilst ditscmd is by
	default still part of this sub-system (which can't use DUL, that
	is later in the build), DUL can rebuild it and re-release it with
	this call enabled.  That will allow ditscmd to translate a much
	larger set of error codes.

ditscmd add q option. ditsgetinfo doesnt output bad status if just looking for a task which isnt there.

        In ditsgetinfo, If checking for a task running, don't output
        the unknown task error if it is not
        just return bad status.  This makes
        creating scripts which check for tasks running easier

        Add -q option to ditscmd, a parameter get which does not use MsgOut
          for output, instead just stdout, for use in scripts.

        ditscmd monitor operations now set the Send-Current flag, so the
          current values are seen on startup.

	All warning now removed when compiled using GCC 5.4 on Linux, mainly
        through the use of DGCC_DIAG_OFF, but also sometimes through
	appropiate casts.

	tasks command now outputs pid and node name.

        Add LISTACTALL and LISTACTACTIVE control messages, simple versions
        of DUMPACTALL and DUMPACTACTIVE which just provide the action
        names.

	DitsStop() ErsOut() calls now include the task name supplied to
		   the call, which allows us to work out which task is
		   outputting the message.

Improve logging around task disconnect and ensuring we return MACHLOST code rather then TASKDISK when we have lost the machine

	Improve logging around disconnection and machine lost messages as
	part of trying to work out an AAO CCD system failure where unexplained
 	disconnections occur.   Basic approach is that if we have a logging
        routine, we log even if the relevant DITS_LOG_BASIC etc. flags are not
	set.  These are rare events so won't dramatically increase the log size.

	Note - now return DITS__MACHLOST status in cases where we used to
	     return DITS__TASKDISC (which was a mistake).

	If DitsLoad() is invoked with a program name greater then
	IMP_MAX_PROG_NAME in length, then it fails immediately, as
	some times the IMP failure can be hard to diagnoise.  Appropiate
	error reporting suggesting the environment variable approach
	is output.

	Fix issue in MsgOut() which was causing crashes if logging was
        enabled and we are in UFACE mode without an ufaceMsgOut routine
        enabled.  Picked up on taipan machine, maybe due to changes in
        compiler or libraries.

	Better error reporting if we fail to fetch parameter names
	setting up a monitor - the previous reporting made it hard
	to work out what had failed, particular for a forward monitor.

	Remove use of now depreciated ERS_M_NOFMT flag, using
	either ERS___M___NOFMT or calling ErsRepNF(), depending on
	the case.

	ditscmd - Explicitly handle trigger messages so that we
                   can support -v for trigger messages and
                   improve the error output.
                  Import error handling for success argument
                   handling failures.

       dits_link.* modified to link libmess.a rather then mess.o

       I have modified IMP to work through NAT, so modify the message
        in the previous version to indicate what to do.  The requirement
        is that the system inside of the NAT environment must set the
        IMP_LOCALNODE_FORCE to the external IP address of the NAT
        router.

	IMP__WRONG_MACHINE messages can be triggered by an attempt to run DRAMA
         through a NAT (Network Address Translation) system.  This doesn't work
         as IMP presumes the IP address of the machine on the other side of the
         NAT system is reachable.

Fix some MacOSX Mavericks warnings. Add macro to allow user to work out if DRAMA_REA_DRAMA2 available

	Add DITS_HAVE_REA_DRAMA2 macro to DitsTypes.h, so that code comiling against
	both old and new DRAMA code and work out what to do with DITS_REA_DRAMA2.

	Fix various compilaing warnings using DGCC_DIAG_OFF()/DGCC_DIAG_ON() macros.

	DitsStop() writes its log message using Dits___Log() rather
		   then DitsLog(), to keep it consistent with other
				internal logging.

	ditsexhand_ux.c  logs under different conditions, consistent
		with mods to DitsStop().

	Add routines DitsTransIdLock() and DitsTransIdUnlocked() to ensure
	    a transaction is not reused too soon (by DRAMA2).

	Bulk data triggers were not getting through, and have not been
	     for years - due to a check in Dits___MsgTap() against the
	     message tag - which has a confusing usage for Bulk data
	     trigger messages.  Set the value to 0 when Dits___MsgTap() is
	     invoked for bulk data messages, which disables the check.

	Modify DitsMsgWait() logging - don't need to output time.

	Add DitsUfaceMsgOut(), and use it to implement Dits___UfaceInfoMess().
	This allows DitsUfaceMsgOut() to be invoked from the DRAMA2 Orphan
	  handler.

	sdptest.C, ditsloadcmd.c, ditsutil.c, dui.c, tocker.c, btocker.c
		tock_sdstest.c, ticker.c, ctest.c, ctest3.c.

		Fix warnings detected by MacOsX mavericks, mainly uninitialised
		variables, but some others as well.

	Add DitsSignalDrama2(), such that we have a special signal for
	    use by DRAMA 2 thread events.  DitsGetEntReason() will return
	    the new code of DITS_REA_DRAMA2.  This will allow us to distinguish
	    user triggered signals from thread completion signals.

	Add DitsSignalExit(), a special signal which causes the mainloop to
	    exit.

	DitsStop will now log a shutdown message with status.

       Modification to VxWorks version of last chage, don't stop option
       processing after task name seen, people have been using that.

        ditscmd.c Changes. Add -- option to VxWorks version (already exists
		  in unix (via getopt()).  Document  -- option in help.
		  Add -w option.

	Fix some compilation warnings picked up by later GCC.

	Removed call to nanosleep under VxWorks in tea.c.

	Ensure I initialise transaction user data to 0 when creating transactions.

    	ditsmonitor.c:DitsMonitorReport() modified to output target details
		for forward monitors.

	Disconnect handlers can now use DitsPutRequest(DITS_REQ_EXIT,status)
	to request that the task exit.

	Add ditswaitexit command - a command which exits when another DRAMA
	task has exited.  Useful in scripts.

Fix notification message handling issues when we have a large number of notifications. Finish getting control messges to output to MsgOut

	Add extra debugging around notifications and add and use
	    DitsGetMsgTypeStr() to output string representations of
	    message type codes.

	Ensure Dits___MsgNotify() handles running out of buffer space
	       whilst processing notifications correctly.

	Ensure transaction ID dumps from control messages written to MsgOut.

		*** ALL Control messages now report to MsgOut rather then stderr.

	Add -h option to ditsloadcmd.  Change to use fprintf() for error
	    messages, it makes it look more like a command line program then
	    using Ers does.

	MsgOut() modified to send a message via reply path even if actionptr is
	equal to -1, this allow messages to be send from CONTROL messages.
	This feature was added to Dits___ErrOut() a long time ago, so should
	be  ok.

	Add Dits___MsgOutOutput() routine to DitsUtil().  Use it as the
	output routine for various routines wanting a Dits output routine,
	so that messages go to MsgOut().

	Various debugging changes.

	*** WARNING - We are not correctly handling large numbers of
	    NOTIFICATIONS.  Seen by using a PRINTENV control message in
	    the new scheme.

	test_basic target in dmakefile needs an extra delay to allow task shutdown
	in some instances.
