+ `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'.
