But presumably this isn't a one size fits all problem but depends on what the user intends to do with Emacs. If configure just informs the user of what functionality will be missing (rather than what libraries are missing), *he* can decide, not us, if that is a problem or not. -- Nick http://www.inet.net.nz/~nickrob
