Fix compile for MinGW (continued)
This fixes the fix in
efe33c61(Fix compile error on MinGW). It only
fixed things on one computer, but apparently not on others. The only
difference between the declarations and function definitions here is the
'internal_function's. if _LIBC is not defined and __i386__ is, then this
actually means something.
