Hi Bernt!

Thanks for your interest in Hamlib. Your feedback on NetBSD 
is very welcome.

Can you try and replace the line 
	#ifdef HAVE_SIGINFO_T
by
	#if defined(HAVE_SIGINFO_T) && defined(SA_SIGINFO)

Hamlib has already been ported to FreeBSD thanks to good folks in the
team. There seems to be some differences between the 2 daemons though.

Mac OS X and some Solaris systems (maybe others) suffer from this problem too.
This means your rpcgen has no support for the hyper data type, ie. 64 bit int.
If you don't need support for RPC backends, you may simply disable it
by passing --without-rpc-backends to configure and rebuild the whole
thing.

Time permitting, there should be a m4 macro in configure.ac to
automatically check for hyper availability, and enable backends
accordingly. This is on the TODO list.

Cheers,
Stephane
