They do rust. Do not be afraid to put some effort on them only 3 things can happen.
1: Strip out screw heads (and/or damage screwdriver) 2: they break 3: they come out
If 1: If the screwdriver sufferes. have it re-sharpened (yes, can be done) 1B: If screw head strips out.. Drill as suggested above and use Vice Grips 2: If it breaks you may be able to get to the top of screw with vice grips or drill it out and go to a slightly larger screw, stainless if possible 3: no problem.
