+
+ * mice.c: Reapply Edmund Grimley Evans' patch with new mouse types
+ ms+ and ms-lr which get lost somewhere.
+
+Sun Sep 13 00:08:54 1998 Ian T Zimmerman <itz@rahul.net>
+

+
+Sat Sep 12 10:53:54 1998 Ian T Zimmerman <itz@rahul.net>
+
+ * Makefile.in (LOBJ): Make the buliding of libcurses.o decided by
+ configure again.
+
+ * libcurses.c (Gpm_Wgetch): Remove the ELF assembler-dependent
+ wgetch hack again, as it is not really needed as long as clients
+ are linked statically.
+
+ * gpm.c (processRequest): Removed GPM_REQ_CLEAR again, now that its
+ functionality is available with the -A flag and opt_aged.
+
+ * gpmInt.h: Removed GPM_REQ_CLEAR again, now that its
+ functionality is available with the -A flag and opt_aged.
+
+ * libxtra.c: Removed Gpm_ClearSelection() again, now that its
+ functionality is available with the -A flag and opt_aged.
+
+ * gpm.h: Removed Gpm_ClearSelection() again, now that its
+ functionality is available with the -A flag and opt_aged.
+
+ * mev.c (interact): Removed "clear" command again, now that its
+ functionality is available with the -A flag and opt_aged.
+
+ * gpmInt.h: Change signature of xfer_options().
+ Remove it altogether, it's better static and split to gpn.c and
+ gpm.c.
+ Add opt_aged.
+
+ * gpn.c (check_uniqueness): Completely rewritten. This function
+ was a messy mixture of different things.
+
+Wed Sep 9 09:50:59 1998 Ian T Zimmerman <itz@rahul.net>
+
+ * libxtra.c (Gpm_GetServerVersion): Provide explicit path for
+ popen of gpm daemon.
+
+ * sample/Makefile.in (rmev.o): Added target because of usage of
+ RMEV_RELEASE.
+ (prefix): Looks like this has to be done in _every_ Makefile,
+ sigh. Even if it is not used explicitly, configure subsitutes
+ e.g. "@sysconfdir@" with "$(prefix)/etc".
+ (sysconfdir): Added sysconfdir.
+
+ * Makefile.in (gpn.o gpm-root.o twiddler.o): gpn.o added to this
+ target because it uses RELEASE symbol substituted by configure.
+
+Tue Sep 8 14:04:44 1998 Ian T Zimmerman <itz@rahul.net>
+
+ * mev.c (interact): Added case for "clear" command.
+
+ * libxtra.c (Gpm_ClearSelection): Added.
+
+ * gpmInt.h (GPM_REQ_CLEAR): Added (rubino's objection overruled;
+ the gpm protocol is not really ugly, it's the code that is, in
+ effect casting the data exchanged to Gpm_Conn and Gpm_Event. It
+ could be coded cleanly or even fixed from present state, but don't
+ hold your breath, you could suffocate.)
+
+ * gpm.h: Add Gpm_ClearSelection.
+
+ * t-mouse.el (t-mouse-swap-alt-keys): Added. This is what is
+ called "personal variable" :-) I swap the left and right Alt keys
+ in my Linux keytable, but I still want Emacs to handle left-Alt
+ events.
+
+Wed Sep 2 00:09:42 1998 Ian T Zimmerman <itz@rahul.net>
+
+ * doc/Makefile.in (maintainer-clean): Ignore errors because the file
+ list can be empty.
+
+ * sample/Makefile.in (maintainer-clean): -rm -i for uniformity.
+
+ * Makefile.in (maintainer-clean): Ignore errors because the file
+ list can be empty.
+
+ * mouse-test.c (makedev): Add O_NONBLOCK to open ttyS devices
+ (otherwise the program hangs in this function, at least on my
+ system).
+
+ * doc/doc.gpm (gpm-root): Use @file at several places in
+ preference to other markup. Fix several other general
+ documentation bugs, mostly referring to obsolete (non-)features.
+
+ * doc/Makefile.in (.SECONDARY): Need both %.ps and gpm.ps ---
+ looks like a gmake bug.
+
+ * sample/gpm-xterm.h: Applied patch by Jean-Daniel
+ <jd@univ-lyon1.fr> for looking back when scanning arrow key
+ sequences.
+

+ elispdir. GNU standard document a little incomplete on this
