 Even if the include files conform to C89, the library itself may not.
 For example, SunOS 4's (free (NULL)) can dump core, so GNULib code
 must avoid freeing a null pointer, even though C89 allows it.
+You can work around some of these problems by requiring the relevant
+modules, e.g., the GNULib 'free' module supplies a conforming 'free'.
 
 The GNU coding standards allow one departure from strict C99: GNULib
 code can assume that standard internal types like size_t are no wider
