Wind River stole them from the Sun Unix distributions.
We can't distribute them in an FSF GDB release.
We should even rewrite them for our own releases, though that is not
as urgent.
Until these two files are rewritten, VxWorks support in GDB will not compile.
The i960 support can be gained by just rewriting the ptrace.h file.
Only small amounts of the reg.h file need to be rebuilt -- compile
remote-vx.c to see what is needed.
