I'm not sure, but maybe it helps stupid compilers to fully understand
whats happening, and maybe suppress a false warning.
For example, this function:
int foo() { if (bar) return 1; else return 0; }
... will trigger a warning in GCC 2.95 because the compiler believes
that not all paths return a result, though they do.
