-* Linking with -rpath on IRIX.
-
-Darrell Kindred <dkindred@cmu.edu> writes:
-There are a couple of problems [with use of -rpath with Irix ld], though:
-
-  1. The ld in IRIX 5.3 ignores all but the last -rpath
-     spec, so the patched configure spits out a warning
-     if --x-libraries or --site-runtime-libraries are
-     specified under irix 5.x, and it only adds -rpath 
-     entries for the --site-runtime-libraries.  This bug was
-     fixed sometime between 5.3 and 6.2.
-
-  2. IRIX gcc 2.7.2 doesn't accept -rpath directly, so
-     it would have to be prefixed by -Xlinker or "-Wl,".
-     This would be fine, except that configure compiles with
-        ${CC-cc} $CFLAGS $LDFLAGS ...
-     rather than quoting $LDFLAGS with prefix-args, like
-     src/Makefile does.  So if you specify --x-libraries
-     or --site-runtime-libraries, you must use --use-gcc=no,
-     or configure will fail.
-
-* On Irix 5.x and 6.x, the dumped XEmacs (xemacs) core dumps when executed 
-  on another machine, or after newer SGI IRIX patches have been installed.
-
-The xemacs binary must be executed with the same "libc.so" file which was used 
-when the xemacs binary was dumped.  Some SGI IRIX patches update this file.
-Make sure that all machines using the xemacs binary are using the same
-set of IRIX patches.  If xemacs core dumps after a patch upgrade then you 
-will have to redump it from temacs.
-
-* xemacs: can't resolve symbol '__malloc_hook'
-
-This is a Linux problem where you've compiled the XEmacs binary on a libc
-5.4 with version higher than 5.4.19 and attempted to run the binary against
-an earlier version.  The solution is to upgrade your old library.
-
-* VM appears to hang in large folders
-
-This is normal (trust us) when upgrading to VM-6.22 from earlier versions.
-Let VM finish what it is doing and all will be well.

-* MH-E and TM can have problems with PGP messages.
