00c5dee16b Include <assert.h>. 
(_longjmp): Ensure that we have at least 4 exception-handling args.  (This code
	will need updating to make it work on x86, where only 2 exception handling
	args are available).
(longjmp): If we are compiling with GCC, use an alias-attribute to alias it with
	_longjmp().  This is more efficient and works around a gcc-3.2/ia64 bug
	which causes bad unwind info when a noreturn function is a last call.

62491cc719 Many fixes to get (remote) dynamic unwind info working for real. 
Add get_proc_name() callback to accessors so things like the ptrace-support
routines can also print static procedure names.
Try running "tests/test-ptrace -v -t tests/ia64-test-dyn1" for fun.
