 ** Linux
-*** Mandrake (all versions)
+*** Mandrake
 
-Cannot be fully supported by XEmacs developers because they insist on
-applying known broken patches.
+The Mandrake Linux distribution is attempting to comprehensively
+update the user interface, and make it consistent across
+applications.  This is very difficult, and will occasionally cause
+conflicts with applications like Emacs with their own long-established
+interfaces.  Known issues specific to Mandrake or especially common:
 
-One known issue is that on keyboards with both a Meta key (typically
-the Windows key on PCs) and an Alt key, XEmacs wants to bind the Meta
-modifier to the Meta key.  Mandrake has a policy that XEmacs
-Meta-chords should use the Alt key, which they enforce by patching
-XEmacs's modifier-handling code, making the Meta and Alt modifiers
-synonymous.  This will break planned upgrades to XEmacs to allow menu
-hotkeys; be warned.  See next topic for how to implement Meta-on-Alt
-portably.
+Some versions of XEmacs (21.1.9 is known) distributed with Mandrake
+were patched to make the Meta and Alt keysyms synonymous.  These
+normally work as expected in the Mandrake environment.  However,
+custom-built XEmacsen (including all 21.2 betas) will "inexplicably"
+not respect the "Alt-invokes-Meta-commands" convention.  See "I want
+XEmacs to use the Alt key" below.
+
+The color-gcc wrapper (see below) is in common use on the Mandrake
+platform.
 
 *** I want XEmacs to use the Alt key, not the XXX key, for Meta commands

 One correct way to implement this was suggested on comp.emacs.xemacs
 (by Kilian Foth and in more detail by Michael Piotrowski): unmap the
 Meta modifier using xmodmap or xkb, and then map the Meta/Windows key
-to the Super or Hyper modifier.  XEmacs will not find the Meta keysym,
-and default to using the Alt key for Meta keybindings.  Typically few
-applications use the (X11) Meta modifier (sawfish is one); it is
-tedious but not too much so to teach them to use Super instead of
-Meta.  There may be further useful hints in the discussion of
-keymapping on non-Linux platforms.

+it is tedious but not too much so to teach the ones you need to use
+Super instead of Meta.  There may be further useful hints in the
+discussion of keymapping on non-Linux platforms.
+
+*** The color-gcc wrapper
+
+This wrapper colorizes the error messages from gcc.  By default XEmacs
+does not interpret the escape sequences used to generate colors,
+resulting in a cluttered, hard-to-read buffer.  You can remove the
+wrapper, or defeat the wrapper colorization in Emacs process buffers
+by editing the "nocolor" attribute in /etc/colorgccrc:
+
+$ diff -u /etc/colorgccrc.old /etc/colorgccrc

+If you want colorization in your Emacs buffers, you may get good
+results from the ansi-color.el library:
+
+http://www.geocities.com/kensanata/color-emacs.html#ansicolors
+
+This is written for the mainline GNU Emacs but the author has made
+efforts to adapt it to XEmacs.  YMMV.
