The OpenBSD system compile, which is based on GCC 3.3.5, already has
the sentinel attribute.

I'm afraid you'll need an explicit cast for the NULLs used as the
sentinel value, otherwise platforms that
#define NULL 0L
will generate warnings like:
sentinel.c: In function 'foo':
sentinel.c:8: warning: missing sentinel in function call
and with -Werror, that's not a good :(.
