Hello,

Is there a reason why the following constants aren’t defined for the  
ruby  
runtime? Is there another way to access them that I’m not finding?

Thanks,

I don’t know if there is a reason but you can look in Config::CONFIG  
once you  
require rbconfig:

% ruby -r pp -r rbconfig -e ‘pp Config::CONFIG’
