Summary:                    [patch] app_stack weak reference not set up properly
for build on Mac OS X
Description: 
On Mac OS X 10.4.11 (latest Tiger) the following is reported during make:

[LD] app_stack.o -> app_stack.so
/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning weak symbol
references not set in output with MACOSX_DEPLOYMENT_TARGET environment
variable set to: 10.1
/usr/libexec/gcc/powerpc-apple-darwin8/4.0.1/ld: warning weak referenced
symbols:
_ast_agi_register
_ast_agi_send
_ast_agi_unregister

and the following is reported during load:
Asterisk Dynamic Loader Starting:
 == Parsing '/etc/asterisk/modules.conf':   == Found
[Jan 11 12:04:24] NOTICE[18378]: loader.c:869 load_modules: 152 modules
will be loaded.
[Jan 11 12:04:24] WARNING[18378]: loader.c:371 load_dynamic_module: Error
loading module 'app_stack.so':
dlopen(/usr/lib/asterisk/modules/app_stack.so, 5): Symbol not found:
_ast_agi_unregister
 Referenced from: /usr/lib/asterisk/modules/app_stack.so
 Expected in: flat namespace

And then Asterisk just hangs.  Workaround is to remove app_stack.so or
just not build it.

No, that patch does not work.  It causes the first prelink to fail with

powerpc-apple-darwin8-gcc-4.0.1: 10.3: No such file or directory

What did work was to explicitly set MACOSX_DEPLOYMENT_TARGET=10.4 before
the make command.  

However, in the meantime the source has been modified.  The version in
trunk (168536) now gets the following compiler warnings, but links ok
without any modifications to Makefile.

   [CC] app_stack.c -> app_stack.o
app_stack.c:683: warning: alias definitions not supported in Mach-O;
ignored
app_stack.c:683: warning: alias definitions not supported in Mach-O;

app_stack.c:683: warning: alias definitions not supported in Mach-O;

app_stack.c:683: warning: alias definitions not supported in Mach-O;
ignored
app_stack.c:683: warning: alias definitions not supported in Mach-O;

However, trunk (168536) doesn't get much farther along before it wipes
out:

   [CC] asterisk.c -> asterisk.o
asterisk.c: In function 'handle_show_sysinfo':
asterisk.c:568: error: storage size of 'vmtotal' isn't known

function)
