All three NCR5380 core driver implementations share the same NCR5380.h header file so they need to agree on certain macro definitions. The flag bit used by the NDEBUG_MERGING macro in atari_NCR5380 and sun3_NCR5380 collides with the bit used by NDEBUG_LISTS. Moreover, NDEBUG_ABORT appears in NCR5380.c so it should be defined in NCR5380.h rather than in each of the many drivers using that core. An undefined NDEBUG_ABORT macro caused compiler errors and led to dodgy workarounds in the core driver that can now be removed. (See commits f566a576bca09de85bf477fc0ab2c8c96405b77b and 185a7a1cd79b9891e3c17abdb103ba1c98d6ca7a.) Move all of the NDEBUG_ABORT, NDEBUG_TAGS and NDEBUG_MERGING macro definitions into NCR5380.h where all the other NDEBUG macros live. Also, incorrect "#ifdef NDEBUG" becomes "#if NDEBUG" to fix the warning: drivers/scsi/mac_scsi.c: At top level: drivers/scsi/NCR5380.c:418: warning: 'NCR5380_print' defined but not used drivers/scsi/NCR5380.c:459: warning: 'NCR5380_print_phase' defined but not used The debugging code is now enabled when NDEBUG != 0.
