[PATCH] Make SIG2STR_MAX usable in #if

[Torbjorn SVENSSON]

  #if __SIZEOF_INT__ >= 4
-#define SIG2STR_MAX (sizeof("RTMAX+") + sizeof("4294967295") - 1)
+#define SIG2STR_MAX 21	/* (sizeof("RTMAX+") + sizeof("4294967295") - 1) */
  #else
-#define SIG2STR_MAX (sizeof("RTMAX+") + sizeof("65535") - 1)
+#define SIG2STR_MAX 17	/* (sizeof("RTMAX+") + sizeof("65535") - 1) */
  #endif


I have not read the specification, but how come it's 17 and 21?

 From what I can tell, "RTMAX+65535" is not 4 shorter than "RTMAX+4294967295".

Kind regards,
Torbjörn
