+  `ptmalloc2', a malloc implementation for multiple threads without

+
+  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
