> Please review this small change to call os:: API's.  the changes were tested with Mach5 tiers 1-2 on Linux, Mac OS, and Windows, and Mach5 tiers 3-5 on Linux x64.  Most of these changes were for I/O related calls.  Changes to memory allocation calls such as malloc and free will be handled in a future change.
