Okay, everything's groovy up to this point. But there's a wreck on the
highway starting here :

* (load "etc/examples/fm.cmucl")

; Loading #p"/home/dlphilp/cm-2.3.4/etc/examples/fm.cmucl".
;;; Running /usr/bin/ld...
;;; Done.
;; Loading #p"/home/dlphilp/cm-2.3.4/etc/examples/fm.x86f".

Error in function UNIX::SIGSEGV-HANDLER:  Segmentation Violation at

  0: [CONTINUE] Return NIL from load of
  1:            Return NIL from load of "etc/examples/fm.cmucl".
  2: [ABORT   ] Return to Top-Level.

Debug  (type H for help)

(UNIX::SIGSEGV-HANDLER #<unused-arg>
                       #.(SYSTEM:INT-SAP #x28295FB8))
Source: Error finding source: 
Error in function DEBUG::GET-FILE-TOP-LEVEL-FORM:  Source file no longer

And when I select 2 I receive an endless series of this message :

	*** Sigsegv in page not marked as write protected

At this point I have to Ctrl-c until I get to the debugger which will
finally let me quit (i.e., none of ABORT processes work).

I'd love to try Xemacs, but the version I've built won't load anything.
It fails telling me :

	"Feature not yet implemented: insert-gui-button requires 'annotations'

and it fails whether I try loading a file from the File/Open menu or
pressing the Open button. <sigh>... I can load a file by specifying it
at startup 'xemacs foo.lisp' but not from within the GUI.
