 libshout (the old version) fails to configure saying:

 Checking `config.log` shows this:

 configure: failed program was:

 #include "confdefs.h"
 #include <stdio.h>
 #include <sys/types.h>
 main()
 {
   FILE *f=fopen("conftestval", "w");
   if (!f) exit(1);
   fprintf(f, "%d\n", sizeof(long long));
   exit(0);
 }
 }}}
 So, it turns out to be another victim of `-Werror=implicit-function-
 declaration` being on by default now.
