win32: Add an fsync() implementation for windows For information on FlushFileBuffers(), see the msdn document at msdn.microsoft.com/en-us/library/aa364439(VS.85).aspx Note that Windows 2000 is shown as the minimum windows version to support FlushFileBuffers(), so if we wish to support Win9X and NT4, we will need to add code to dynamically check if kernel32.dll contains the function. The only error return mentioned in the msdn document is ERROR_INVALID_HANDLE, which is returned if the file/device (eg console) is not buffered. The fsync(2) manpage says that EINVAL is returned in errno, if "fd is bound to a special file which does not support synchronization". Signed-off-by: Ramsay Jones <ramsay@ramsay1.demon.co.uk>
