Hi Jeremy,

Yes, this is a known issue, documented in README.Debian: 
https://salsa.debian.org/js-team/emscripten/-/blob/debian/latest/debian/README.Debian#L50

Thanks for the suggestion.  I wonder if such change will actually be any 
better: I very much doubt that the horribly old closure-compiler 
available in Debian can do *anything* sensible, but would be happy if 
proven wrong.

Did you test that suggested change, using closure-compiler in Debian?

Sounds like you have some knowledge/experience here.

I am open to improving README.Debian, but will need help: Please provide 
suggestions for rephrased text.


Kind regards,

 - Jonas
