	This happens in Borland C++ v 5.5 (C++ Builder 5 with patch).

	I'll suggest to change lcode.h:

lcode.h Line 42:

extern  const struct OpProperties {
  char mode;
  unsigned char push;
  unsigned char pop;
} luaK_opproperties[NUM_OPCODES];  /* <-------- */

	This keeps borland happy and should be compatible with others
compilers.

	I hope that lua authors include this in next release.

	Regards.
