2007-08-11
	- Added, "value," instance variable as the default in all
	  class definitions, and a check in eval_expr () for 
	  results that are only instance variable, in which case
	  the function creates a new object with a copy of the
	  instance variable result of another method call.  Added
	  the library function __ctalkIsInstanceVariableOf () to
	  check for the presence of an instance variable.
	- Ctpp 1.0.9.
2007-08-13

	  if a method returns an object or only an instance 
	  variable.

	  expressions.
	- Added getChar (class Character) method.

	  stack before using frame pointers.
	- Added, "include once," section in ctalk.texi.

	- Added argv0.exp, argv0.c, argv.c, and argv.exp in 
	  test/expect.
	- Added test/ and test/expect directory contents to EXTRA_DIST
	  in top-level Makefile.am. Subdirectory test/ contains a 
	  non-autoconf Makefile.
	- Added better ctpp warning for inability to find the GCC 
	  library subdirectory, and the GCC_LIBDIR environment 
	  variable has its own section in ctpp(1).
	- Added noinst_HEADERS in top_builddir Makefile.am.
	- Release 0.0.10a.

2007-09-17

	  objects are only in the right-hand term of the expression.
	  Added for for loop termination predicates.

	- Fixed up while loop code so the predicates always evaluate
	  into run time expressions, either evaluated in default_method
	  (), if the expression begins with a C variable and operator,
	  or in loop_block_end () in loop.c.  
	- Added while1,c, while1.exp, while2.c, while2.exp, while3.c, and

	- Updated method_call () in method.c and default_method () in 
	  rexpr.c for compound methods.
2007-09-23

	- Added get_class_method () and is_class_method (), and added
	  class method lookups to the instance method lookups in 
	  method.c, class.c, and rexpr.c; and changed method lookup
	  errors to exceptions.
2007-09-24
	- Added argument promotion in __ctalk_primitive_method ()

	  initialization.
2007-09-27

	  contexts at run time in resolve_arg ().
2007-10-01
	- Substitute __ctalk_arg_internal () calls in new_object if
	  the argument is a method parameter.  Calls to format the
	  __ctalk_arg_internal () calls correctly for __ctalk_arg (),
	  __ctalk_primitive_method (), __ctalk_method (), and 
	  __ctalk_set_local ().
	- Add the result objects of constructor calls to the global
	  dictionary in __ctalk_method (), rt_methd.c.
	- Added get_class_variable () function in object.c.

	- Fixed class variable access functions and made sure that
	  all primitive methods get treated similarly, except for,
	  "new."  Fixes to handle class objects and objects with

	  in the interpreter and run time library.

	- Added readChar, readLine, and openOn methods and 
	  stdinStream class variable (class ReadFileStream).
2007-10-06
	- Added close method (class ReadFileStream).
	- Ctpp 1.0.17.
	- Added class WriteFileStream methods classInit, value,
	  new, openOn, close, writeChar, and write, and 
	  stdoutStrea and stderrStream class variables.
	- Changed the arg() macro in ctalklib and ctldjgpp to
	  ARG().
	- Changed __ctalk_set_local () so it takes an OBJECT
	  as its first parameter, so the name doesn't get
	  confused with the value.
	- Added errno instance variable to the FileStream
	  class definition.
	- Release 0.0.13a.
2007-10-12	
	- Speedups - fixed gnu_attributes to stop at first semicolon;
	  temporarily removed the global_cvar search from get_function.
	- Added _hash_all () in chash.c.
2007-10-13

	- Added compatibility function gnuc_fix_empty_extern ()
	  to elide empty declarations that cause compiler warnings.
	- Fixed a bug in remove_method_arg_cvar () that prevented
	  retrieving a function's local C variable (rt_cvar.c).
	- Removed the formatting of __ctalkEvalExpr call into
	  array subscripts in subscript_expr () (rexpr.c).  
	  Subscript_expr () now creates a template that derives
	  an integer subscript from the ctalk expression, and uses
	  that to set the method argument to the correct array 
	  element.
	- Added leading_unary_op () (control.c) which sets the 
	  start of an if statement predicate to the leading 
	  operator if one exists, or simply the original start
	  (usually the opening parenthesis).  Does not handle
	  predicates that start with semicolons, so only works
	  in if, while, and do statements.
	- Added while4.exp, while4.c, do4.exp, and do4.c in
	  test/expect to check negated object predicates.
2007-10-16
	- Added streq.c.
	- Added class and superclass OBJECT * members to OBJECT 
	  type.  Use the superclass OBJECT * in obj_method_by_fn (), 
	  and __ctalk_get_object () (rt_obj.c); and in the method
	  find method functions in method.c.
	- Basic syntax checking of instanceVariable arguments 
	  (primitives.c).
	- Changed the names of the FileStream instance variables so
	  they do not conflict with stdio names.
	- Added exceptions for glibc error numbers 1-34, using the text
	  of asm-generic/errno-base.h, with gettext macros.
	- __ctalkSysErrExceptionInternal calls __ctalkExceptionInternal.
	- Added FileStream: eof method.
	- Added end-of-file checks for ReadFileStream methods, and
	  exceptions generated by __ctalkSysErrExceptionInternal if
	  there is an error.
2007-10-17
	- Code cleanup for lint-type warnings, bugfix that re-initializes
	  e_class in _eval_expr () (rt_expr.c).
	- Release 0.0.14a.
	
2007-10-22
	- Ctpp 1.0.19. Changes to configuration files: Added the
	  gccincdir.sh script to add the path during configuration
	  to the ctpp AM_CFLAGS without needing to specify the
	  path as an option to configure.  Added the gccincdir.sh
	  script to EXTRA_DIST in Makefile.am.
	- Fixed a memory allocation bug in create_tmp () (tempio.c).
2007-10-25

	  minor speedups.

	- Added -finline-functions optimizatin in src/Makefile.am,
	  lib/Makefile.am, and configure.in.  Also added 
	  -without-inline-functions option to configure.in.
2007-11-02
	- Release 0.0.16a.

	- Added ctcc script.
	- Release 0.0.30a.
2007-12-24

	  checks for two consecutive labels and changes the 
	  next label to METHODMSGLABEL if necessary.
