Bugs in profiling and C compile on PDP-11

This is NOT a bug in cc, it's a bug in the profiling stuff,
the compiler is correct in doing a signed shift, if the shift is to be unsigned,
the code should be:
	(unsigned)(( ... ) >> 1)
and NOT	(unsigned)( ... ) >> 1,

(casts having higher precedence than shifts).
