I'll bet that the assembler is taking the 'r0' references in the TAS()
snippet to be a global-variable name, rather than register name as
intended. Possibly $0 or %0 or some such locution is needed.

The VAX port has evidently not been used in a long time. I had noticed
that it was inconsistent with all the other ports in defining slock_t
in s_lock.h rather than in the OS-specific header files; that's clearly
wrong now.

Feel free to submit a patch once you get it worked out.
