One way to make fstat() and stat() consistant would be to have fstat()
call stat().  There must be some way to ask DOS for the pathname
associated with the file pointer that fstat() gets, but I'm not a DOS
expert so I don't know how to do that.

About st_blksize:

Isn't 512 the true disk blocksize?  If not, is 4096 always the correct
value, or does it vary depending on how the disk is layed out?  Is
there a way to ask DOS and fill this field in correctly?
