Jens Eden converted recDynLink to EPICS 3.14, and I've made a
few trivial modifications from the code he sent me.  I don't know
on what platform(s) the code has been run, or even if it has been
run.  I'm converting most of synApps (which includes recDynLink with
modifications to support ca_put_callback links), but I haven't tested
anything yet.

For the record, recDynLink was the original implementation (by Marty
Kraimer) of retargetable links.  Now that all EPICS links are retargetable,
it's probably preferable to use standard links, unless you want a
(putNotify) callback when the execution your link started completes.
Note that the version of recDynLink in base has never had this
capability, so if you've been using the version from base, you
can switch to standard links.  We still need recDynLink for the sscan and
swait records, because they must wait for processing they start to finish,
and I plan to write a version of the seq record with the option of waiting
until processing started by one link has finished before firing the next link
in the sequence.  We've been doing this with sequences of swait records often
enough to know that the capability will get used.

In any case, I'm sending you the recDynLink code in a separate
email.  (I don't think the whole list needs a copy of this code
right this minute.  It will be included in the first 3.14-compatible
version of synApps.)
