[zroncroe] 64-bit main

long main(){}

compiled on an x86_64 system: main-return.cpp:1: error: '::main' must return 'int'

Too bad; we seem to be stuck with 32-bit return values from processes ($?) forever.

Though the shell seems to limit to 8 bits with echo $?

#include <cstdlib>
int main(int argc,char**argv){
  if(argc>1){
    return atoi(argv[1]);
  }
}
