+ Fix problems on 64-bit Windows. Avoid warnings, some of which
+ indicated actual problems, some which were just annoyances.
+
+ Where casts to an integer type are needed for pointers, use
+ gssize. Technically intptr_t would be the more proper type, but we
+ still want to be compilable with MSVS6 and 7 which don't have
+ intptr_t. MSVS8 and 9 do have intptr_t, but in <crtdefs.h>, not
+ <stdint.h>.
+
+ Use %p to print out handles. Use gssize casts when assigning
+ GPollFD::fd fields.
+
+ Use G_GSIZE_FORMAT when printing size_t values.
+
+ * configure.in: Define automake conditional G_OS_WIN32_X64 which
+ is true on Win64.
+
+ * glib/giochannel.h: Use slightly different prototype for
+ g_io_channel_win32_new_messages() on Win64 with gsize instead of
+ guint.
+
+ * glib/giowin32.c
+ * glib/gmain.c
+ * glib/gspawn-win32.c
+ * tests/testglib.c: Generic changes as described above.
+
+ * glib/gmain.h: Don't bother mentioning GIMP in comment.
+
+ * glib/grel.c (tuple_hash_2): Use all bits of pointer.
+
+ * glib/gspawn-win32.c
+ * glib/gspawn-win32-helper.c: Use gssize types in the
+ communication between parent and helper process, so that we can
+ pass process handles, which are pointers, also on Win64.
+
+ * glib/gtimer.c (g_time_val_to_iso8601): time_t is 64 bits on
+ Win64 so we can't pass the address of a GTimeVal::tv_sec which is
+ a long directly to gmtime(). On the other hand, changing
+ GTimeVal::tv_sec to be a gint64 on Win64 is not really feasible
+ either, as that would then require changes in much code that uses
+ GTimeVals.
+
+ * glib/gspawn-win32.c
+ * glib/Makefile.am: Call the helper programs
+ gspawn-win64-helper.exe and gspawn-win64-helper-console.exe on
+ Win64, to avoid potential risk of running a 32-bit version of the
+ helper.
