be careful running .c files. if you don't know what they do, you can cause great danger
if you don't have make installed, you should get it. there are make rpms out there - check
www.rpmfind.net
just so you know, make is for installing files, generally. if you see just random files around and don't know what they do, don't run make on them - i'm not exactly sure what would happen, but it may not be that pretty.
(god, i haven't used linux in a long time!)
