apr_file_read never hits EOF under Vista with Overlapped I/O

Apparently under Windows Vista, the read_with_timeout() call does not handle the case where the error is ERROR_IO_PENDING, the WaitForSingleObject() completes, but GetOverlappedResult() sets the nbytes value to zero.
 
For the normal branch, if nbytes is zero the return value is set to APR_EOF.
 
For the Overlapped case (readwrite.c line 96) the return value is always set to APR_SUCCESS.  Under Windows XP, the code works fine.  But under Windows Vista the code needs to check for nbytes being zero, and for that case setting the rv value to APR_EOF.
