	* PERFORMANCE: use a packed cache to speed up tcmalloc
	* PORTING: preliminary windows support! (see README.windows)
	* PORTING: better support for solaris, OS X, FreeBSD (see INSTALL)
	* Envvar support for running the heap-checker under gdb
	* Add weak declarations to maybe_threads to fix no-pthreads compile bugs
	* Some 64bit fixes, especially with pprof
	* Better heap-checker support for some low-level allocations
	* Fix bug where heap-profiles would sometimes get truncated
	* New documentation about how to handle common heap leak situations
	* Use computed includes for hash_map/set: easier config
	* Added all used .m4 templates to the distribution
