Curses detection. Swap library link order in sieve to make sure dependacies are…

… caught right.  Add errno.h to mailutils/Makefile.am for make release

+2002-02-21  Jeff Bailey  <jbailey@outpost.dnsalias.org>
+
+	* sieve/Makefile.am: Link @ARGPLIBS@ before libmailutils.la to 
+	compensate for lack of interlibrary dependancies
+
+	* configure.in: Detect either curses or ncurses
+
+	* include/mailutils/Makefile.am: Add errno.h
