Experimental Physics and
Industrial Control System

Have the past 9 years yielded any clarify on support for '__thread'?  I
believe vxworks is the only blocker to use of '__thread', aka.
'__declspec(thread)' aka. 'thread_local'.

Title:
  vxWorks 6.8 deprecates the use of taskVarLib

Status in EPICS Base:
  Triaged

Bug description:
  The release notes say the taskVarLib facilities will be removed in a
  future release, and they don't work on SMP systems anyway.

  The __thread storage class replaces taskVarLib.  It's not clear if any
  vxWorks releases before 6.8 support __thread variables though.

  Someone will have to modify src/libCom/osi/os/vxWorks/osdThread.c to
  comply with this.
