	No.
	"some_string" is a char pointer which is initialized to point
	to "some string" every time "do_somthing" is called. It (the
	pointer) is in the stack. If it needs to be static the declaration
	would be:
	static char *some_string="some string";
	Where "some string" actually is is up to the compiler writer. The
	two places I can think of off-hand are:
		- in the code
		- in some hidden global data area
	Would some one who's written a C compiler comment on this?
