* gtk/gtkaqua.c (gtk_aqua_draw_focus): Don't crash if "detail" is
NULL.
* gdk/MacCarbonEvents.c (mouse_motion_handler): Another NULL
pointer check.
2006-04-17 Gwenole Beauchesne <gb.public@free.fr>
* glib-1.2.10/gmain.c (g_main_run): Don't block in
RunApplicationEventLoop(), code inspired from Inside Mac
technote.
This patch only suits Basilisk II needs. i.e. this may not work
for other programs.
2006-04-17 Gwenole Beauchesne <gb.public@free.fr>
* glib-1.2.10/glibconfig.h (G_VA_COPY): Don't redefine.

* Under Mach there is very little assumed about the memory map of object
* files. It is the job of the loader to create the initial memory map of an
* executable. In a Mach-O executable there will be numerous loader commands
* that the loader must process. Some of these will create the initial memory
* map used by the executable. Under Darwin the static object file linker,
* ld, automatically adds the __PAGEZERO segment to all executables. The
* default size of this segment is the page size of the target system and
* the initial and maximum permissions are set to allow no access. This is so
* that all programs fault on a NULL pointer dereference. Arguably this is
* incorrect and the maximum permissions shoould be rwx so that programs can
* change this default behavior. Then programs could be written that assume
* a null string at the null address, which was the convention on some
* systems. In our case we need to have 8K mapped at zero for the low memory
* globals and this program modifies the segment load command in the
* basiliskII executable so that it can be used for data.
