I'm a software developer.  If tool chains are broken, I try to fix them
or get them fixed.  My time is way to precious to be wasted on broken
tools.  Rather I spend it on getting tools to do what I need.

Sincere condolences if you have to work in such an environment.

But even then, this is not a reason to break the code for people who
are in a more lucky position.

Is it? And how so?  And why would this not be the default setting,
then?


Mike, please state clearly if you have a solution for the current
problem, or I will just revert that commit.

Best regards,
