 MAIL LOCKING
 ============
 
-Find out what the preferred method for locking mail spool files is in
-your environment.  Presently, XEmacs supports lockf, flock, and dot
-locking.  Specify the locking method via the --mail-locking=METHOD
-option to configure.  Valid values for METHOD are --mail-locking are
-`lockf', `flock', and `dot'.
+For most platforms, configure or the src/s file have the preferred
+method for locking mail spool files preconfigured.  Otherwise you must
+find out for youself.  Do not choose a locking protocol "on the
+objective merits."  XEmacs must use the same method as other mail
+utilities on your system, or you will lose mail.

 ** Linux
-*** Mandrake
-
-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:
-
-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.
+*** XEmacs crashes on startup, in make-frame.
+
+Typically the Lisp backtrace includes
+
+   make-frame(nil #<x-device on ":0.0" 0x2558>)
+
+somewhere near the top.  The problem is due to an improvement in GNU
+ld that sorts the ELF reloc sections in the executable, giving
+dramatic speedups in startup for large executables.  It also confuses
+the traditional unexec code in XEmacs, leading to the core dump.  The
+solution is to use the --pdump or --ldflags='-z nocombreloc' options
+to configure.  Recent 21.4 and 12.5 autodetect this in configure.
+
+Red Hat and SuSE (at least) distributed a prerelease version of ld
+(versions around 2.11.90.x.y) where autodetection is impossible.  The
+recommended procedure is to upgrade to binutils >= 2.12 and rerun
+configure.  Otherwise you must apply the flags by hand.  --pdump is
+recommended.
