I keep a fairly close eye on them and they tend to be all spurious messages due to the fact that the assembler has an incomplete understanding of the code (and its invariants). The compiler should generate more directives to help the assembler, but the code itself is generally correct. I think gcc3.1 may be a bit better. I only get 2 or 3 spurious messages with it (apart from some that are due to inline asm, which are harder to avoid). --david
