In fact, 5.1.4 compiles fine in C++ mode.

Here is the first error i get from DEV-C++ (the compiler stops but I can 
get other errors like this one by compiling other files):

---
g++.exe -c lua-5.2.0-work1/src/lapi.c -o lua-5.2.0-work1/src/lapi.o

lua-5.2.0-work1/src/lapi.c: In function `void lua_arith(lua_State*, int)':
lua-5.2.0-work1/src/lapi.c:303: error: invalid conversion from `int' to 
`TMS'
lua-5.2.0-work1/src/lapi.c:303: error:   initializing argument 5 of 
`void luaV_arith(lua_State*, TValue*, const TValue*, const TValue*, TMS)'
---

The offending line is:

  luaV_arith(L, L->top - 2, L->top - 2, L->top - 1, op - LUA_OPADD + 
TM_ADD);

casting the last argument to TMS make it compile:

    luaV_arith(L, L->top - 2, L->top - 2, L->top - 1, (TMS)(op - 
LUA_OPADD + TM_ADD));

There are other lines like this in lcode.c (I didn't test further).
