Although -Wmain-return-type is not considered as error (unlike
-Wimplicit-int on gcc 14 and clang 16), but just a warning, let's fix it
for the future.
<stdin>:1:1: warning: return type of 'main' is not 'int' [-Wmain-return-type]
While at it, add missing void.

Changes v1->v2:
* keep int return type on a separate line (Zack. I still wonder why :))
NOTE: there are places where int is not on a separate line:
#ifdef __cplusplus
#include <stdio.h> /* for printf() prototype */
int main (int argc, char *argv[]) {
#else
int main (argc, argv) int argc; char *argv[]; {
#endif
* add void (Zack)
