   That's not clear.  Linux (since 2022) guarantees argc>=1.  I don't   
   know whether Windows makes a similar guarantee, but it's entirely   
   plausible that it could.   
      
   But not all systems guarantee argc>=1, so any portable code shouldn't   
   make assumptions beyond what's guaranteed by ISO C.
