I confirm this bug.  I could reproduce it even if MC if compiled with
large files support (default for the CVS version).

Here's the fix:

--------------------------
--- cmd.c
+++ cmd.c
@@ -1420,7 +1420,7 @@ dirsizes_cmd (void)
 	         strcmp (panel->dir.list [i].fname, "..") != 0) {
 	    total = 0.0l;
 	    compute_dir_size (panel->dir.list [i].fname, &marked, &total);
-            panel->dir.list [i].buf.st_size = (long)total;
+	    panel->dir.list [i].buf.st_size = (off_t) total;
 	    panel->dir.list [i].f.dir_size_computed = 1;
 	}

--------------------------

It will only work if large file support is enabled, but it's now the
default (in CVS), and those disabling it must accept the consequences.

By the way, I think that using double instead of off_t in several places
is an overkill.  It should be sorted out later.  I think that double was
used as an alternative to adding 64-bit file support.  As it often
happened in the MC history, of all possible solutions the first one to
work (somehow) was used.

This works correctly with the current version.  I don't care how it works
if mc is configured with --disable-largefile

I must disappoint you.  I have never seen a single patch for the GNOME
frontend coming from users (i.e. not from Ximian employees).  People may
like it, but nobody in the whole world likes is so much to learn some
programming and improve it.

The GNOME frontend is only left in the stable branch, from which mc-4.5.56
may (or may not) be released.  The head branch leading to 4.6 already has
GNOME support removed.

I'm not going to improve anything in the GNOME frontend due to lack of
interest from users.  I'll only apply patches from others.
