I think the attached patch file solves it.

I am trying to get it done right now.

But unfortunately after updating core/master, it does not compile any
more for my host architecture.
And the day end in 7 minutes.

I probably send you a patch file instead of what I thinks should work.

Hi Dirk,

Michael and I need to know exactly what changes you still need to be
committed for the VxWorks 6.3 and/or 6.7 builds that are not already in
our repositories. Posting the output from 'git diff' rather than just a
description like this is much better, it ensures we don't miss anything.
If you can do that TODAY we'd appreciate it, we're wanting to tag the
-rc1 release, and we'd prefer to have your changes included if possible.

Thanks,

- Andrew

Contact support@windriver.com for instructions.

This can be fixed by using the non-__GNUC__ version for __GNUC__ < 4

#if !defined __GNUC__ || __GNUC__ < 4
#  define SHOW_EXCEPTION(EI) ::epics::pvData::detail::showException(EI)

With that change, I could finally build EPICS 7 for vxWorks 6.3.
(Thus the boost header spinlock_pt.hpp is not obsolete.)
