That relies on someone having converted the vxWorks symbol support to use
the R3.14 symbol registration routines (which I don't believe has been
done yet, but I might be wrong there), and Josh would still have to
register the address of his debug variable with the registration
facility.  It should be possible to do that within a device support
initialization routine rather than having to write the C++ static
initializer routine that Eric was describing, but Eric's solution is
probably simpler overall until vxSymb gets properly converted to R3.14.
