2006-01-30Move SUSv2 obsolete feature disabling to debug menu, invert meaning ofRob Landley
symbol (switched on to remove now: test your apps to make sure they _don't_ do this, because as some point we should just yank it), fixup head/tail/fold. Also tweak "make allyesconfig" so anything starting with CONFIG_DEBUG gets left switched off. Possibly other things we want to put in the debug menu?

Fix the compilation of head and tail. thanks!

option handling to be disabled. Defaults to enabled, so no changes in default behaviour
