+ * Makefile.in (m68k_tdep_h): Define.
+ (abug-rom.o, cpu32bug-rom.o, dbug-rom.o, m68k-tdep.o, m68klinux-nat.o)
+ (remote-est.o, rom68k-rom.o): Add $(m68k_tdep_h).
+ * m68k-tdep.c: Move register number enum ...
+ * m68k-tdep.h: ... to this new file and rename the constants from
+ E_* to M68K_*. All uses changed.
+ * config/m68k/tm-m68k.h (D0_REGNUM, A0_REGNUM): Remove definitions.
+ * abug-rom.c: Include "m68k-tdep.h". Use
+ M68K_D0_REGNUM/M68K_A0_REGNUM instead of D0_REGNUM/A0_REGNUM.
+ * cpu32bug-rom.c: Likewise.
