Changes:
Todo:
- Strings.
- asm statement.
- Complete attribute support.
- Forward module declarations.
- Allow static array definitions.
- Inheritance.
- Optimize generation of messages sent to "this".
- Finish string reference counting.
- Fix -dleak

20030531:
- Fixed attributes used on literals.
- Fixed "continue" when used within a "for" loop.

20030529:
- Added the -dleak switch. This can be used to find memory leaks.
  It doesn't always work correctly right now...

20030528:
- Added partial reference count support for strings.

20030527:
- Added reference count field to strings. Not yet used.
- Fixed -v option.
- Fixed handler return type so that it isn't always an integer.

20030526:
- Made float argument passing conform better to the ABI.
  (It is now necessary to use the 'data attribute when passing floats
  to system calls).
- Implemented the float ^ operator.

20030524:
- More work on the thread support.
- Added character to string conversion.
- Added integer to string conversion.
- Added float to string conversion.
- Added pointer to string conversion.
- Added boolean to string conversion.

20030521:
- Began adding thread support.

20030519:
- Fixed a nasty bug related to the SetSymbolUnused function.

20030517:
- Fixed a bug in the delete statement that caused core dumps when
  deleting an array of objects.
- Fixed a minor bug with the new operator.
- Fixed initial values in comma separated declarations.
- Fixed an obscure bug related to arrays.

20030516:
- Changed != to /=.
- Removed ! for not.

20030515:
- Fixed a few minor bugs.

20030512:
- Added most type conversion attributes.
- Fixed floating point return values.
- Fixed argument passing (still may have problems with more than 8).

20030511:
- More support for strings.
- More bug fixes.

20030502:
- String arguments now supported.

20030428:
- Improved code generation for the subtract instruction.
- Implemented indexing characters in strings.
- Fixed a bug causes problems in some generated code.
- Implemented storing characters in strings.

20030427:
- Improved code generation for the add and multiply instructions.
- The argument to "main" is now really of type string[].
- Added the 'data attribute to access the raw data of an object.
- Implemented the 'name attribute.
- Allow an indexed object to be used to invoke a handler.
- Fixed the "-o" option.

20030426:
- Float support completed.
- Multi-size function arguments are now allowed.
- Changed the argument encoding.

20030423:
- Added min and max float attributes.
- Cleaned up register allocator.
- An arbitrary number of handler arguments are now supported.
- Passing floats to handlers is now supported.

20030422:
- Fixed problem causing variable corruption related to temporary reuse.

20030421:
- Changed the "next" keyword to be "continue". This keyword isn't likely
  to be used often and "next" is a popular variable name.
- Added the values "true", "false", and "null".

20030420:
- Fixed another problem with the new/delete handlers.

20030417:
- Added import search path.
- Fixed problem with modules and the new operator.
- new and delete operators should now work as expected.

20030227:
- Reverted reuse of temporaries - causes too many problems.

20030226:
- Types now supported within modules.
- Object and module support completed.

20030225:
- Objects (instances of modules) supported.
- Problem when a module has no handlers and a handler is invoked fixed.

20030224:
- Support for command line arguments.
- Reuses temporaries.
- switch, when, and default statements implemented.
- Integer power operator now works.
- Support for multiple modules.

20030223:
- Attributes partially implemented.
- No longer outputs constants that aren't used.
- Fix bus error when the "length" attribute is used on an array element.
- maze.j compiles and works.

20030222:
- Improved stack frame calculations.
- Fixed bus errors/segmentation faults at exit in some programs.
- Partial float support.
- Arrays within arrays.

20030221:
- Arrays.

20030220:
- Fixed argument passing.
- Overloaded handlers now work.
