I was trying to uninstall gcc... not easy, I must say: I cycle one element to "Uninstall", but as soon as I touch an element that requires that one, the first one changes to "Keep". Also, it seems that gcc-java depends on gcc-mingw-java and also the reverse so, in fact, it's currently impossible to deinstall all of gcc in a single setup-1.7 execution.
I don't know, maybe instead of "rolling between choices" they should be drop down menus? This way I could "jump" directly from "current version" to "Uninstall" without cycling thru "upgrade" (and subsequent "Keep" of all requirements). -- Lapo Luchini - http://lapo.it/ “Violence is the last refuge of the incompetent.” (Isaac Asimov, "Foundation", 1942-05)
