#defineMDB_DEBUG0
       Enable debug output. Needs variable argument macros (a C99 feature). Set this to 1 for copious tracing.
       Set to 2 to add dumps of all IDLs read from and written to the database (used for free space management).

   #defineDPUTS(arg)DPRINTF(('%s',arg))
       Print a debug string. The string is printed literally, with no format processing.

   #defineDDBI(mc)(((mc)->mc_flags&C_SUB)?-(int)(mc)->mc_dbi:(int)(mc)->mc_dbi)
       Debugging output value of a cursor DBI: Negative in a sub-cursor.
