Not really important, maybe it is simply a coding style question..
I came across some switch-cases (e.g. line 339, vdr.c):
case SOME_VALUE: : return SOME_CODE; break;
The "break" isn't required.
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.
