Unfortunately, with some compilers (gcc, I'm looking at you) you get considerably fewer warnings with -O0 than with -O1, even if you specify -Wall. The reason seems to be that some of the warnings need information produces by some of the optimization passes.
I usually use -O1 for debug builds, these are usually still at least somewhat debuggable with gdb.
