   12: 
   13:         * process.c (send_process_1):
   14:         If pipe buffer is full, wait a second and try again.

   16: 1986-05-02  Richard M. Stallman  (rms@prep)
   17: 
   18:         * termcap.c (tputs): Round rather than truncating
   19:         when dividing padcount.

   27: 
   28:         * alloca.c: Declare xmalloc.

   33:         a specified buffer.  Use in Fdelete_buffer_internal

   35: 
   36: 1986-04-14  Richard M. Stallman  (rms@prep)
   37: 
   38:         * alloc.c (malloc_warning, Fgarbage_collect):
   39:         If malloc_warning is called during GC, just save warning
   40:         in malloc_warn_string.  Try again to warn when GC ends.

   52: 
   53:         * indent.c (compute_motion):

   56:         Introduced macros HPOS and VPOS for extracting components of cpos.
   57:         Alternate HPOS definition for Celerity since casting to (short)

   97: 
   98: 1986-03-24  Richard M. Stallman  (rms@prep)
   99: 
  100:         * xfns.c (Fx_proc_mouse_event):

  111:         * fileio.c (Fsubstitute_in_file_name):

  115: 
  116:         * unexec.c (make_hdr): Avoid comparing a_bss field with 0.

  146: 
  147:         * s-usg*.h, s-unipl*.h:

  200: 
  201:         * s-hpux.h: Turn off HAVE_PTYS since their csh has "sanity
  202:         checking" and other programs seem to lose with ptys.

  240: 
  241:         * s-usg*.h: #define static as nothing.
  242:         * m-hp200.h: No longer needs to #define static.
  243: 
  244:         * unexec.c (adjust_lnnoptrs):
  245:         Replace dummy defn with one that does the job.  Also
  246:         involves including syms.h and making global vars
  247:         bias and lnnoptr that are set in make_hdr.
  248: 
  249: 1986-03-08  Richard M. Stallman  (rms@prep)
  250:

  284:         (change_msgs): Deactivate them here, when notification is done.

  720: 
  721:         * lread.c:
  722:         Change condition for defining X_OK to be that X_OK is not defined.
  723: 
  724:         * alloc.c (init_alloc_once):
  725:         Fix erroneous names data_bytes_{un,}used
  726:         inside the VIRT_ADDR_VARIES conditions.
  727: 
  728:         * emacs.c:
  729:         Don't include time.h or resource.h; just #define PRIO_PROCESS.
  730: 
  731:         * xdisp.c (redisplay_window):
  732:         Don't shift window-start to avoid end of buffer
  733:         unless window contents have changed too.
  734: 
  735:         * xdisp.c (DoDsp):
  736:         If nothing has changed except minibuffer message,
  737:         no need to call redisplay_window.
  738: 
  739:         Problem: standard sysV has no file ioctl.h.
  740: 
  741:         * process.c, keyboard.c, dispnew.c, sysdep.c:
  742:         Include ioctl.h in BSD, termio.h and/or fcntl.h in sysV.
  743: 
  744:         * callproc.c: No longer needs ioctl.h; don't include.
  745:         * xdisp.c: No longer needs ioctl.h or signal.h; don't include.
  746: 
  747:         * emacs.c:
  748:         Include sys/ioctl.h only for BSD.  ioctl used only in BSD.

  751: 
  752:         * keyboard.c (EchoThem):
  753:         Always display an explicit prompt, even if echo_keystrokes == 0.
  754: 
  755: 1986-01-21  Richard M. Stallman  (rms@prep)
  756: 
  757:         * keyboard.c (kbd_buffer_store_char, fake_suspend):
  758:         Take the STRIDE code for subshell out of kbd_buffer_store_char
  759:         and call it fake_suspend.  Call it from previous place and
  760:         also from Fsuspend_buffer, on all systems that lack SIGTSTP.
  761:         Clean the code up a little bit.
  762: 
  763:         * process.c:
  764:         Don't include sgtty.h; no longer needed.
  765:         Make use of wait3 depend on existence of WNOHANG.
  766: 
  767:         * unexec.c:
  768:         Allow the m- file to override defn of ADDR_CORRECT (m-stride.h does).
  769:         Have and use pagemask to round data_start in COFF case too.
  770:         Always define getpagesize as macro, for 4.1 and USG where
  771:         it is not provided as a system call.
  772:         This takes care of the STRIDE changes for unexec.
  773: 
  774:         * ymakefile:
  775:         Give ld the arg $(STARTFLAGS), and define that based on cpp macro
  776:         TEXT_START_ADDR when that is defined.  This is for systems where
  777:         the -T switch is necessary.
  778: 
  779:         * unexec.c (make_hdr):
  780:         Make one sun3 fix machine-independent.
  781:         (Prevent a_bss from being negative).
  782: 
  783:         * casefiddle.c (casify_region):
  784:         New flag value CAPITALIZE_UP which is like CAPITALIZE
  785:         but changes only the initials.  Function upcase_initials_region
