Re: can use zip library on Linux but not on Windows

[marks]

That link is helpful, thank you. For anyone else who hits this, I added these 
two lines after the imports: 
    
    
    when defined(windows):
      {.passl: "-lz".}
    
    
    Run

It now compiles & runs & lists zip contents on Windows and Linux. And the 
executable doesn't seem to depend on any separate shared libs, so is 
conveniently stand-alone.
