[AL] override_config_file doesn't seem to work in 4.2

[Chris La M. <cel...@ch...>]

Please pardon me if this has been addressed, I couldn't find it in the
archives....

I (finally!) upgraded from Allegro 4.1.18 to 4.2.0; now override_config_file
doesn't seem to work.  If I use set_config_file instead, my config file
works but with override_config_file it's ignored.  Is this a known problem?

On a related note, I can't find any updates or patches against 4.2.0;
everything I can find is on 4.3.x.  Are the 4.2 patches available publicly?

Thanks!
