+
+       Do not tickle glib SIGCHLD handling if Cygwin (Bug#14569).
+       This mostly consists of undoing recent changes.
+       * callproc.c (Fcall_process):
+       * process.c (create_process):
+       Do not worry about catching SIGCHLD here, undoing previous change.
+       * nsterm.m (ns_term_init): Re-catch SIGCHLD, undoing previous change.
+       * process.c, process.h (catch_child_signal):
+       No longer extern if !NS_IMPL_GNUSTEP, undoing 06-22 change.
+       * process.c (catch_child_handler): Don't worry about being called
+       lazily and do not assume caller has blocked SIGCHLD, undoing
+       previous change.  Move first-time stuff back to
+       init_process_emacs, undoing 06-22 change.  If CYGWIN, do not
+       tickle glib, as that causes Cygwin bootstrap to fail.  Do not
+       set lib_child_handler if it's already initialized, which may
+       help avoid problems on GNUStep.
+
+2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+       A more-conservative workaround for Cygwin SIGCHLD issues (Bug#14569).
+       * callproc.c (Fcall_process):
+       * process.c (create_process):
+       Make sure SIGCHLD is caught before we fork,
+       since Emacs startup no arranges to catch SIGCHLD.
+       * process.c (lib_child_handler): Initialize to null, not to
+       dummy_handler.
+       (catch_child_signal): Allow self to be called lazily.
+       Do nothing if it's already been called.
+       Assume caller has blocked SIGCHLD (all callers do now).
+       * emacs.c (main): Do not catch SIGCHLD here; defer it until
+       just before it's really needed.
+       * nsterm.m (ns_term_init): No need to re-catch SIGCHLD here,
+       since it hasn't been caught yet.
+
+2013-06-23  Lars Magne Ingebrigtsen  <larsi@gnus.org>
+
+       * image.c (compute_image_size): New function to implement
+       :max-width and :max-height.
+       (imagemagick_load_image): Use it.
+
+2013-06-23  Paul Eggert  <eggert@cs.ucla.edu>
+
+       Try to avoid malloc SEGVs on Cygwin (Bug#14569).
+       * callproc.c, process.h (block_child_signal, unblock_child_signal):
+       Now extern.
+       * emacs.c (main): Catch SIGCHLD just before initializing gfilenotify.
+       * process.c (catch_child_signal): Block SIGCHLD while futzing with
+       the SIGCHLD handler, since the code is not atomic and (due to glib)
+       signals may be arriving now.
+       * sysdep.c (init_signals): Do not catch child signals here;
+       'main' now does that later, at a safer time.
+
 2013-06-22  Paul Eggert  <eggert@cs.ucla.edu>
 
        Clean up SIGCHLD handling a bit (Bug#14569).
