+	* eval.[ch] (scm_deval_args):  Made static.
+
+	* srcprop.c (scm_source_property):  Remove redundant SCM_IMP
+	test.
+
+	* strings.c (scm_c_string2str):  Clarified comment.  Replaced
+	THINKME by FIXME for uniformness.  Removed question about whether
+	arguments need to be protected from garbage collection:  Arguments
+	must be protected as any other variable.
