* Makefile.in (gencode): Depend upon gencode.o, getopt.o, and
getopt1.o, rather than on gencode.c. Link objects together. Don't link against -liberty. (gencode.o, getopt.o, getopt1.o): New targets. * gencode.c: Include <ctype.h> and "ansidecl.h". (AND): Undefine after including "ansidecl.h". (ULONG_MAX): Define if not defined. (OP_*): Don't define macros; now defined in opcode/mips.h. (main): Call my_strtoul rather than strtoul. (my_strtoul): New static function.
