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.
