Hello!

I've compiled 1.6.4 for mswin32 almost succefully. Microsoft's compiler
passed with some warnings. Intel's icl 4.5 issued a lot of errors in
parse.y, because of the following fragment:

#if SIZEOF_LONG_LONG > 0
typedef unsigned long long stack_type;
#elif SIZEOF___INT64 > 0
typedef unsigned __int64 stack_type;
#else
typedef unsigned long stack_type;
#endif

I've removed the fragment except "typedef unsigned long stack_type;" (
since I do want the stack be unsigned long :).

I'm disappointed with a lot of warnings wich I prefer to call "errors":
"the function must return a value".
Intel's compiler could not vectorize most of loops :(

But... I like Ruby!
