	      is valid only at where definitions are allowed)

	      in scm_s_define())

	      !SCM_STRICT_DEFINE_PLACEMENT. Since it breaks the R5RS internal
	      definitions semantics, the macro is replaced with
	      SCM_USE_INTERNAL_DEFINITIONS and the feature is made exclusively
	      selectable from only 'completely valid' or 'disabled'. The
	      broken internal definitions have been withdrawn
	  - (scm_s_define):

	Add test for the case where call-with-values calls itself as the

	unwarranted considering the rarity of this corner case.

	* This commit adds a testsuite for the proper tail
	  recursion. This test must be run by special method to take
	  effect. See header comments of the file.
	
	  Current SigScheme implementaion does not have at least two R5RS
	  compliant behavior about the proper tail recursion feature. The
	  'and' and 'or' conditionals is not properly tail-recursive (tests
	  for them are provided by this file).
	
	  See "3.5 Proper tail recursion" of R5RS and please fix it, Kazuki.

	* Applied patch by Jun Mukai <jun.lambda@gmail.com>
	  Thank you!
	
	* sigscheme/sigschemetype.h
	  - add parenthesiss to the c-macro argument
	* sigscheme/eval.c
	  - (ScmExp_cond): return SCM_UNSPECIFIED when no tests become true
	    value
	  
	
2005-08-03 kzk <mover@hct.zaq.ne.jp>
	
	* fix "do" behavior
	
	* sigscheme/eval.c
	  - (ScmOp_do): each <step>s' execution result must not depend on
	    each other. so we need to allocate new space for storing each
	    results and set it by hand.
	
	* sigscheme/test/test-exp.scm
	  - add testcase for "do"
	
2005-08-03 kzk <mover@hct.zaq.ne.jp>
	
	* implement "Named let"

	  - (ScmExp_let): implement named let
	  - (ScmExp_let_star): use add_environment correctly
	* sigscheme/test/test-exp.scm
	  - add testcase for named let
	
2005-08-03 kzk <mover@hct.zaq.ne.jp>
	
	* added files foc SLIB configuration. Now, SLIB path is directly written in the code.
	  we need to autogenerate the path to SLIB.
	
2005-08-03 kzk <mover@hct.zaq.ne.jp>
	
	* fix "letrec" behavior
	* fix "repl" behavior

	    and SigScm_gc_unprotect_stack. this prevents stack_start_pointer
	    to become null in gc phase. 
	
2005-08-02 kzk <mover@hct.zaq.ne.jp>
	
	* sigscheme/test/test-apply
	  - add testcases for dot list arg

2005-08-01 kzk <mover@hct.zaq.ne.jp>
	
	* fix "letrec" behavior
	
	* sigscheme/eval.c

	    ScmExp_set also evaluates the 2nd argument.
	
2005-08-01 kzk <mover@hct.zaq.ne.jp>
	
	* sigscheme/read.c

	    But seemingly, SEGV of "bench/bench-case.scm" and "bench/bench-let-loop.scm"
	    caused by the bug of GC. So, I changed the heapsize and heapnum to the small
	    value for debugging purpose.
