Jlint changelog:

Version 2.3: (Trivial) port to LinuxPPC and Mac OS X.

Version 2.2: Applied Eric A. Raymond's compiler compatibility
patch. Removed -DHASH_TABLE in the Makefile due to some problems (it
can still be enabled if needed). OpenBSD port (thanks to Kevin Lo for
testing it).

Version 2.1: FreeBSD Port (thanks to Ernst de Haan for giving me access
to a FreeBSD box), Visual C++ port (by Maarten Breddels).

Version 2.0: As a part of Cyrille Artho's master thesis, 2 1/2 weeks
were spent on cleaning up and extending Jlint as follows:

	- Jlint has been restructured into several files. All larger
	classes now are in their own file, while some smaller classes
	have been grouped by their meaning. This makes Jlint easier
	to maintain.

	- Synchronized blocks are now fully supported. The value of
	references is tracked during their "life" on the stack and
	as static or instance variables. This allowed the following
	improvements:

		1. wait/notify[All] calls are now truly checked: The
		current set of locks is analyzed. Depending on whether a
		thread holds the lock it is wait()ing on or whether it
		holds other locks, too, different (much more precise)
		warnings are issued.

		2. Inter-method deadlocks from synchronized blocks
		are fully checked. The call graph analysis has been
		extended with "pseudo method calls" whenever a lock
		is being obtained. This extends the old analysis for
		synchronized methods.

		3. Assignments to locking variables (usually hazardous)
		are also checked. If they are not within a constructor
		or guarded by a lock, a warning is issued.

Version 1.11: Last version from Konstantin Knizhnik, using one source
and one header file.
