For your information, the VxWorks part has lots of compilation errors that
need fixing (I'm working on it).
Your Makefile.in part does not include changes for VxWorks either.

I'm working on fixing these and testing on VxWorks, and plan to commit the
s-interr-hwint.adb and *vxworks.ad? changes, as well as enabling
s-interr-hwint for VxWorks, but since there were many errors, I'd rather
not make RTEMS changes blindly, so I'll let you commit RTEMS specific
changes once I've committed the generic and VxWorks parts.
