But 322197*32768/4096 is. And I think that's the order of the values.

As I said, with the cvs code, you'd get the same results as earlier
versions of DJGPP (with free space < ~2GiB of course). Probably it
hasn't ever been accurate, or it's more accurate than chkdsk...

By the way did you use the already present #if 0-ed code (i. e. you
changed the 0 to 1)? I'm talking about this:
#if 0
      printf("Second: bsize = %ld, free = %ld, blocks = %ld.\n"
           , bsize
           , free
          , blocks
             );
#endif

I want to know because if you didn't we could just as well remove it.

Your patch submission look alright this time.

I will test.


Thank you!
