Update to 1.4.0:

 Changes between 1.3.1 and 1.4.0 (12-Sep-2003 to 02-Sep-2005)

  *) Optimize insertion of free memory chunks by merging with
     the spare area if possible to decrease memory fragmentation.

  *) Fix mm_realloc() function: If the memory chunk passed to mm_realloc()
     can't be extended and a new chunk must be allocated, the old memory
     is copied into the new chunk with a call to memcpy(3). However, the
     used size is the length of the new data and will cause memcpy(3) to
     access memory beyond the old data chunk's boundaries.
     [Kirk Petersen]

  *) Upgraded build environment to GNU Libtool 1.5.20 and GNU shtool 2.0.2
     [Ralf S. Engelschall]

  *) Updated all copyright messages for year 2005.
