-/* Support for reentrant syscalls. The "struct _reent *" arg is always the
- the first one. After that we allow up to four additional args. We could
- allow more, but that's all we need for now.
-
- It may seem inefficient to have the reent arg be the first one as it means
- copying all the other args into place (as opposed to making the reent arg
- the last one in which case there wouldn't be any copying). I chose a clean
- design over an extra four instructions in a system call. All other
- reentrant functions use the first arg this way. */
