I thought asyn was programmed in C, not C++?

Yes, we are still using 5.4.2 and we have not yet decided whether to upgrade
VxWorks or rather switch to RTEMS. We may decide this year, but it is not
clear how long it will take use to complete the upgrade/switch, once the
decision is made. I would not be happy if it turns out we can no longer
compile new versions of asyn, especially since many modules depend on it
(e.g. most of the stuff in synApps).
