[xemacs-hg @ 2002-05-23 11:46:08 by ben] fix for raymond toy's crash, alloca crashes, some recover-session improvements files.el: Recover-session improvements: Only show session files where some files can actually be recovered, and show in chronological order. subr.el, menubar-items.el: As promised to rms, the functionality in truncate-string-with-continuation-dots has been merged into truncate-string-to-width. Change callers in menubar-items.el. select.el: Document some of these funs better. Fix problem where we were doing own-clipboard twice. Makefile.in.in: Add alloca.o. Ensure that alloca.s doesn't compile into alloca.o, but allocax.o (not that it's currently used or anything.)

Repeat to self: 2^21 - 1 is NOT the same as (2 << 21) - 1. Fix crashes due to excessive alloca(). replace alloca() with ALLOCA(), which calls the C alloca() [which uses xmalloc()] when the size is too big. Insert in various places calls to try to flush the C alloca() stored info if there is any. Add MALLOC_OR_ALLOCA(), for places that expect to be alloca()ing large blocks. This xmalloc()s when too large and records an unwind-protect to free -- relying on the caller to unbind_to() elsewhere in the function. Use it in concat(). Use MALLOC instead of ALLOCA in select-msw.c. xemacs.mak: Add alloca.o.

  Whether you should use sun1, sun2 or sun3 depends on the
		   VERSION OF THE OPERATING SYSTEM
  you have.  There are three machine types for different versions of
  SunOS.  All are derived from Berkeley 4.2, meaning that you should
  use -opsystem=bsd4-2.  Emacs 17 has run on all of them.  You will
  need to use sun3 on Sun 2's running SunOS release 3.

  For SunOS release 4 on a Sun 3, use -machine=sun3 and
  -opsystem=sunos4.  See the file share-lib/SUNBUG for how to solve
  problems caused by bugs in the "export" version of SunOS 4.
