* config/i386/tm-go32.h (TARGET_LONG_DOUBLE_BIT): Remove definition (and use the common one in tm-i386.h). (REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Likewise. (I386_DJGPP_TARGET): Don't define, it's no longer required. (LOW_RETURN_REGNUM, HIGH_RETURN_REGNUM): Remove definition, i386-tdep.c defines it for all x86 targets. (LD_I387, HEX_LONG_DOUBLE_INPUT): Remove. * config/djgpp/fnchange.lst: Add i386-linux-tdep.c. * config/djgpp/djcheck.sh: Edit the copyright year out of the test results. Fix editing of `main' arguments for non-GNU Sed.
