+        emacs_write: Accept and return EMACS_INT for sizes.
+        See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html
+        et seq.
+        * gnutls.c, gnutls.h (emacs_gnutls_read, emacs_gnutls_write):
+        Accept and return EMACS_INT.
+        (emacs_gnutls_write): Return the number of bytes written on
+        partial writes.
+        * sysdep.c, lisp.h (emacs_read, emacs_write): Likewise.
+        (emacs_read, emacs_write): Remove check for negative size, as the
+        Emacs source code has been audited now.
+        * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
+        (emacs_read, emacs_write): Use it.
+        * process.c (send_process): Adjust to the new signatures of
+        emacs_write and emacs_gnutls_write.  Do not attempt to store
+        a byte offset into an 'int'; it might overflow.
+        See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html
+
+        * sound.c: Don't assume sizes fit in 'int'.
+        (struct sound_device.period_size, alsa_period_size):
+        Return EMACS_INT, not int.
+        (struct sound_device.write, vox_write, alsa_write):
+        Accept EMACS_INT, not int.
+        (wav_play, au_play): Use EMACS_INT to store sizes and to
+        record read return values.

         * keyboard.c (Qundefined):  Don't declare static since it is
