adapting the source to one or the other is straightforward, but
what is the correct fix to make it work with both versions of
the API? Including spread_params.h and checking SP_*_VERSION
sort of defies the purpous of SP_version, especially since a
binary using the wrong interface will most likely segfault.

The concrete case is spreadlogd-1.4.1 (hi Theo ;). Since we're
linking against the spread libs statically anyway, I used the
attached patch. I'm sure there is a cleaner way to fix this,
though :)
