[BUG] Lua 5.2 on PowerPC64

[Elizabeth Kammer <eakammer@...>]

Hi, I've run into issues attempting to run Lua on PowerPC64, resulting in a the following ERROR:

PANIC: unprotected error in call to Lua API (bad conversion number->int; must recompile Lua with proper settings)

PowerPC64 can now be Little Endian, so I believe the issue can be resolved by updating luaconf.h to check for endianness as follows:

<code>

/* pentium 64 bits? */

#elif defined(__x86_64)                                         /* }{ */

#define LUA_IEEE754TRICK

#define LUA_IEEEENDIAN 0

+ #elif defined(__powerpc64__) || defined(__PPC64__)            /* }{ */

+ 

+ #define LUA_IEEE754TRICK

+ 

+ #if defined(__LITTLE_ENDIAN__)

+ #define LUA_IEEEENDIAN                0

+ #else

+ #define LUA_IEEEENDIAN                1

+ #endif

+ 

#elif defined(__POWERPC__) || defined(__ppc__)                  /* }{ */

</code>

Thanks,
