+       mark functions with const and pure attributes
+
+       Mark functions per suggestions from gcc-4.6 when using these options:
+       -Wsuggest-attribute=pure -Wsuggest-attribute=const.
+       Use gnulib's _GL_ATTRIBUTE_PURE and _GL_ATTRIBUTE_CONST macros.
+       Follow these guidelines: when possible, apply the attribute to
+       an extern declaration, not to its definition.  Apply it to the
+       definition only when the definition is static.
