The prototype has to come from libiberty since the system doesn't have  
strsignal:

/* Return a signal message string for a signal number
    (e.g., strsignal (SIGHUP) returns something like "Hangup").  */
/* This is commented out as it can conflict with one in system headers.
    We still document its existence though.  */

/*extern const char *strsignal (int);*/
