+ `ptmalloc', a malloc implementation for multiple threads without
+ lock contention, by Wolfram Gloger <wmglo@dent.med.uni-muenchen.de>.
+ See the files `ptmalloc.c' or `COPYRIGHT' for copying conditions.
+
+ VERSION 2.6.4-pt Wed Dec 4 00:35:54 MET 1996
+
+ This work is mainly derived from malloc-2.6.4 by Doug Lea
+ <dl@cs.oswego.edu>, which is available from:
+
+ ftp://g.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
+ `ptmalloc.c'.
