 * Apparently GetFileAttributes 3.51 sometimes gets confused when the
 * file in question is on a FAT drive.  Since FindFirstFile seems to
 * work, use it instead.
 *
 * Implementation with FindFirstFile / FindNextFile
 * has bug for root of drive due to they can not work
 * with it.
 * Now (2009-01-31) this code is not used for Windows NT >= 4
 * it call native GetFileAttributes
 * We hold this problematic code for compatibility with 3.51 even if
 * nowdays it is very archaic system.
