Good catch!  Fixed.

I don't think that --without-slang is supposed to be used.  Use
--with-ncurses to use ncurses and nothing to use S-Lang.  Ideally, MC
should have one option --with-screen=(slang|ncurses), like Lynx.

Thank you for taking time to test all that.

I knew that.  The charset patch is doing it wrong.  I'm applying a quick
fix:

---------------------------------
--- main.c
+++ main.c
@@ -1841,8 +1841,13 @@ setup_pre (void)
 {
     /* Call all the inits */
 #ifdef HAVE_CHARSET
-    int full_eight_bits = (display_codepage != 0 && display_codepage != 1);
-#endif
+/*
+ * Don't restrict the output on the screen manager level,
+ * the translation tables take care of it.

+#define full_eight_bits (1)
+#define eight_bit_clean (1)
+#endif /* !HAVE_CHARSET */

 #ifndef HAVE_SLANG
     meta (stdscr, eight_bit_clean);
---------------------------------

I'm really don't like the idea of MC asking the user, not the terminal
library, whether 8-bit characters are allowed.  It's another example when
the first working (somehow) solution is the solution used in the code.  I
hope that I'll be able to do it better some day.
