Here is line 229 of /usr/include/string.h:

---
extern char *strerror (int __errnum) __THROW;

Here is an extract of /usr/include/sys/cdefs.h, the place where __THROW
is defined (there is one other definition in /usr/include/malloc.h):

---
#ifdef __GNUC__

   to help it optimize the function calls.  But this works only with
   gcc 2.8.x and egcs.  */
