sim/ppc/words.h has 3 typedefs enclosed in #ifdef __GNUC__, but I dont see
anything in the typedef that will require this #ifdef.
#ifdef __GNUC__
typedef long long natural64;
typedef signed long long signed64;
typedef unsigned long long unsigned64;
#endif
The xlc compiler fails to see any other definition of natural64, signed64
and unsigned64 and reports them as undefined. Is it ok to remove this
#ifdef ?
I can change #ifdef __GNUC__ to #if, #else statement to accomodate
_MSC_VER .
Thanks

If you want to remove the ifdef, you need to find another way to test
whether long long is available. Many C89 compilers do not support it.
