What does `stat' return in the `struct stat'?  Does it think this is a
file? a directory? a volume label?  If it's a directory, does it seem like
`stat' decides it's a root directory (the inode number is 1 for root
directories)?  Which bits did `stat' set in the `_djstat_fail_bits'
variable?

To test the above, you might take stat.c from the library sources and
compile it with -DTEST.  It will produce an executable test program which
you should invoke thusly: 

	stat 0 file ...

(0 is the value of the bit-mapped variable `_djstat_flags' that controls
the behavior of `stat'; it is documented in the library on-line docs). 
The program will then stat each of the files from the command line and
print (most of) the contents of `struct stat', together with a
human-readable description of the bits set in `_djstat_fail_bits'.  Please
post the info so that I could isolate the problem (I don't have access to
a WinNT machine).
