    sgmlpre/sgmlpre.l: Fix some "type defaults to 'int'" warnings.
    
    There are some places where plain static is used, triggering a warning
    if [-Wimplicit-int]. Use static int, it is anyway what the compiler is
    considering. Same for main with no return type.
    
    warning: type defaults to 'int' in declaration of 'whatever' [-Wimplicit-int]
      static nest;
      static ifsense;
      static firstoff;
    
    warning: return type defaults to 'int' [-Wimplicit-int]
      main(int argc, char *argv[])
