ok.  many people have been  having problems with emacs under SunOS
4.1, and we have not seen the FAQ list for a while (which has all the
answers).  So, here is my set of patches that i have collected that
make GNU Emacs work just fine under SunOS 4.1, even under X when
started via rsh (no controlling terminal.)

Fixes to GNU Emacs 18.55 for SunOS 4.1

apply these patches to ..../emacs-18.55/src using the patch program:

  patch < emacs.patches

where emacs.patches is this file.  the patch to alloc.c is needed for
getting gcc -traditional to compile emacs properly (at least on a sparc.)
the fix to malloc.c is to get around a SunOS 4.1 bogon where the localtime
function scribbles beyond the amount of memory it requests. be sure to
#define SUNOS_LOCALTIME_BUG in the config.h file.  the patch to process.c is
needed for spawning sub-processes from emacs.  in particular, shells started
within emacs will suspend themselves if this patch is not applied. these
patches have only been tested on a SPARCStation 1.

i have collected these patches from USENET (mostly gnu.emacs.bugs). if you
have any problems, read that newsgroup.  if you don't have access to it,
then (and only then) send me e-mail and i'll see what i can do for you.

these are the original sources for the fixes as best i can determine:
 process and localtime patch: Eirik Fuller (eirik@elf.tn.cornell.edu)
 gcc patch (alloc.c): Michael Meissner (meissner@osf.org)
