This is a known misfeature of the current `malloc': it adds a 4-byte
overhead to the requested size and then rounds up the result to the
nearest integral power of 2.  The next DJGPP release will have a
different implementation of `malloc'.  You can find several
experimental versions on DJ Delorie's site,
http://www.delorie.com/djgpp/.  Or you can use some alternate
implementation of `malloc' that is available from the net.  Check the
DJGPP mail archives for some pointers.
