M_ts, M_syd and errSymbolAdd() were all removed from errMdef.h in the
same commit, 0fdb995a0bda9a7d9591b6c2b1bde5b2aab43421 (which occurred on
the 7.0 branch before the 7.0.1 release), so if either macro doesn't
exist you /will/ need to include the new header file errSymTbl.h for the
routine to be declared. My suggestion above was based on my knowledge of
the code's history.
