Hmm, I don't think this is same issue as in the original post and the
problem could be fixed by simply fixing the linker line so that there is
(at least one) -lrumpnet_sockin before -lrumpnet.

I'll testbuild sun2 tomorrow unless someone beats me to it (ENOTIME
today, sorry).

If my analysis above is correct, that would fix linking but not
functionality on sun2.

Additionally, it would break functionality on ~all platforms.  The dynamic
linker has a limitation which makes it unable to handle more than one
linkset per dynamic library.  If you try to use more than one, all but the
first on the linkline are lost.  This will hopefully be fixed by having
everything as a dynamic module in the future (dlopened instead of linked).

thanks for the notice,
