No, it defaults to kilobytes.

du uses inode numbers to detect links, so it will only count a file
once.  The cygwin implementation of inode numbers is bogus.
You might want to build a version of du.c with the inode hashing
commented out.  Also, the implementation of ST_NBLOCKS is wrong.  You
can better results from du by using the -b flag for bytes or the -h flag
for "human readable".
