When attempting to compile emacs versions 21.3.50 or 22.0.50 under FC4,
the process fails with the below messages:
Dumping under names emacs and emacs-21.3.50

or something similar is in effect. The dump may

Here's what I tried and what happened
1. I was attempting to compile either emacs 22.0.50 from CVS download or
emacs 21.3.50 from source file "emacs-21.3.50-20041117.tar.gz"
(available at
http://sourceforge.net/project/showfiles.php?group_id=17203&package_id=35022&release_id=78364)
2. I issued "setarch i386 ./configure". This worked without error messages.
3. I then issued "setarch i386 make bootstrap". This failed with the
following messages

I also tried several other things, like issuing " echo 0 >
/proc/sys/kernel/exec-shield' " to turn off exec-shield completely
before compiling. This didn't work also.
Both of these versions of Emacs compiled under FC3, using the above process.
