Defining TEVENT_NUM_SIGNALS as (2 * SIGRTMIN) so that SIGNAL-based AIO handling on FreeBSD works

I am canvassing opinions on whether there is a better way to do this.
Currently, the default AIO stuff in Samba does not work on FreeBSD
because TEVENT_NUM_SIGNALS is set to 64 and there is a check to see
that the signal number used by the AIO stuff does not exceed this
However, if RT_SIGNAL_AIO Is not set, then:
/* The signal we'll use to signify aio done. */
#define RT_SIGNAL_AIO (SIGRTMIN+3)
in source3/smbd/aio.c but on FreeBSD
/usr/include/sys/signal.h:#define SIGRTMIN 65
So, things do not work.
One solution is to define TEVENT_NUM_SIGNALS as 2 * SIGRTMIN ...
On Linux SIGRTMIN is 32.
Can anyone suggest a better fix?
