I am not aware of any inherent linit on  the  size  of  a  standalone
application.   Of   course   I   assume   that  your  application  is
well-behaviong, i. e. you do check the return codes of all  functions
that might return error codes (like malloc()), you don't overflow the
stack  by  allocating  vast  amounts  of dynamic data or running into
deeply recursive routines, etc.

You will have to modify the link command and/or use a  custom  linker
