* nm-hp300bsd.h (ATTACH_DETACH, PTRACE_ATTACH, PTRACE_DETACH): define.

Browse source 
* m68k-pinsn.c (BREAK_UP_BIG_DECL, AND_OTHER_PART):  #if __GNUC__,
define to kludge the large opcode table into two smaller tables,
since GCC take exponential space to build the table.  Lint.
(NOPCODES):  Remove, use "numopcodes" from opcode/m68k.h instead.
