Yes, in which case everything is supposedly already configured by the
administrator suitably.

Because it was not expected. I definitely can't point to any other user
tool that, being installed in /opt/cross/bla-bla-bla/, would read
configuration file from /etc/. Maybe I just didn't meet one yet.
However, GCC, being most close to FPC by its application, definitely
doesn't behave like that.

Currently? Apparently very little. Specifications sometimes change
though.

Anyway, I'm not trying to insist on anything or trying to re-design
configuration policy for FPC, just shared my feelings.
