Define this to be an expression that returns zero if the given frame is
an outermost frame, with no caller, and nonzero otherwise. The default
definition is nonzero if the chain pointer is nonzero and given frame's
PC is not inside the startup file (such as @file{crt0.o}). The
alternate default definition (which is used if
