-  $Id$
-  `ptmalloc2', a malloc implementation for multiple threads without
-  lock contention, by Wolfram Gloger <wg@malloc.de>.
-
-  VERSION 2.7.0
-
-  This work is mainly derived from malloc-2.7.0 by Doug Lea
-  <dl@cs.oswego.edu>, which is available from:
-
-                 ftp://gee.cs.oswego.edu/pub/misc/malloc.c
-
-  This trimmed-down header file only provides function prototypes and
-  the exported data structures.  For more detailed function
-  descriptions and compile-time options, see the source file
-  `malloc.c'.
