I am trying to create a make file for a package of source code written in
ansi-C everything seems to compile ok except for one code fragment.  see
below. this  code always produces  this warning 

context.c: In function `go_deep':
context.c:34 warning: function returns  address of local variable

the code it is complaining about is as follows -

static char *go_deep(void)
/*
 *	Mark an area deep in the stack
 */
{
int	i;

	return((char*) &i);
}



I am not sure exactly what this code is used for in the package since the
user never sees it, but it look s to me like gcc is complianing about the
code doing exactly what it is supposed to be doing. Since this package
allows you to do non-preemptive multi-processing I think it would be handy
to have since fork isn't working yet, can anyone help me out with
suggestions on how to get rid of this error?
