I use "-O2" all the time. I also use "-finline-functions" and
"-fomit-frame-pointer". I've even tried "-funroll-loops". Works fine
for me on programs of low to medium complexity. I haven't tried on
anything major. I haven't compared to see if "-O2" really improves
anything. (Does the 386 even have a frame pointer?)
