4.9d -- Mon Jun 15 16:46:34 PDT 2009 -- Tim Mann

* Fixed gcc warnings.

* Some small cleanups to reset and power-on.

* Added a workaround to a current X bug that made F11 repeat
infinitely. See http://bugs.freedesktop.org/show_bug.cgi?id=21454.

* Added a keybinding help window contributed by Branden Robinson.
Press F11 to see the help.

* Fixed one more spot that was assuming "char" is signed by default.

* Changed mem_read() to automatically mod the address by 0xffff.
Requiring callers to take care of that was ugly and error prone.
A bug report from Kevin P. Rauch alerted me to the fact that at least
one caller to mem_read_word() wasn´t doing it, causing segfaults.

* Added patch from Branden Robinson so that extra Enter events
synthesized by the X unclutter app (or potentially other X apps, I
guess) don´t cause xtrs to lose track of whether to reenble X key
repeat when the cursor leaves the xtrs window.

* Added patch from Joe Peterson and Ulrich Mueller that makes
NEWDOS/80 boot up knowing the date and time, similar to the existing
feature for LDOS.

* Added assignment to a volatile to the delay/autodelay loop. Without
this some compilers will optimize the loop into nothingness, so it
fails to delay. Thanks to Ulrich Mueller and Joe Peterson.

* Fixed a bug I introduced in 4.9b, where the KBWAIT feature would
stop working after F7, F9, or F10 was pressed. Thanks to Joe Peterson
for a bug report and analysis.

* Deleted all SIGIO code. The code was a kludge to begin with and it
no longer worked with current X libraries and Linux kernels, causing
xtrs to hang. It was also reported to cause hangs when xtrs was
compiled for Windows using Cygwin. Thanks to Howard Pepper, Dennis
Lovelady, Arumin Nueckel, Christopher Currie, and Joe Peterson for bug
reports.

* Replaced "Last modified" lines in source files with RCS $Id$
keywords. It´s been years since I´ve had the DEC SRC macros that
update these lines loaded in my emacs, so they don´t stay up to date.
And I´ve kept the file history in RCS for even more years.
