GCC can optimize sibling-calls; that's a class of tail-calls where the
argument count of the callee and caller are the same.  Other tail-calls
are difficult to optimize, because most systems prescribe a the
caller-pops-arguments calling convention (including the varargs stuff).

Last time I checked LLVM, doesn't even optimize sibling-calls.
