8e6205aca6 * changed the visibility of the writeport and readport methods in the ports unit 
objects to private (since they should be accessed only through the default
  indexed property)

26a3ac3fd4 * moved the fpc_in_x86_*port* constants to the system unit in cpuinnr.inc in the 
i8086, i386 and x86_64 rtl directories. This is done for consistency with
  other compiler internal function numbers (which are declared in innr.inc).

e3ea46d1cb * disable SSE optimized Frac() for Win64; it has a much lower supported range than the existing Pascal implementation which uses Int() (in essence Round() and Trunc() should be corrected as well)
