Hi Neal,

Thanks very much for your tip.  I've been studying makefiles to find out
exactly what all this means.  It may be because the Minix make program
is less capable than gmake.  gmake and other make programs can
obviously handle this.  Configure might have run incorrectly or both
rules are one and the same on Minix, because there is no LDSHARED or
signalmodule$(SO).  Maybe...

Still working on it, but this has narrowed it down for me, so thanks
heaps. :)
