+       The system regcomp() and regexec() routines are very badly

+       We are also hearing reports that Solaris 2.4's NLS libraries
+       dump core with mutt when using a locale different from "C".
+       Use the --with-included-gettext configuration switch if you

        Color does not work right with Solaris curses.  You will have to
        compile with either ncurses or slang to get working color support.
