dbpoll() is defined in dblib.c, but is not implemented.  It is
now guarded by DBLIB_UNIMPLEMENTED.  

If you define that symbol, I suspect OpenDBX will compile and link.
However, it may not *work* correctly because all the function does is
check its arguments.  If OpenDBX doesn't call it, I recommend removing
references to it.  If it does call dbpoll(), it should either be
modified not to, or someone will have to implement the function.
