M_powerpc_darwin needs OBJ_CHAIN_REVERSE_ORDER

Hello dear GNU Prolog developers,

I Built GNU Prolog 1.3.1 on my iMac G5 (ppc) running Mac OS X 10.4.11  
with the usual "./configure" and "make" which did not give any errors  
or warnings.
Running "make test" however gave the following error:

   error: objects are initialised from 1st to last (should be from  
last to 1st)
   define constant OBJ_CHAIN_REVERSE_ORDER in obj_chain.h

Following the suggestion I changed the last lines of "src/EnginePl/ 
obj_chain.h" from

   #if defined(_MSC_VER) || defined(M_ix86_darwin)
   #define OBJ_CHAIN_REVERSE_ORDER
   #endif

to

   #if defined(_MSC_VER) || defined(M_darwin)
   #define OBJ_CHAIN_REVERSE_ORDER
   #endif

and all tests succeeded.
