Thanks very much.  Under solaris2 the  load statement becomes

ld -G misc.o random.o ars.o -o mylib.so


A general question about inconsistencies: is *any* inconsistency
between R and S (not documented, as this one *was*, so apologies)
worth mentioning here in r-help or would that be an annoyance?  
Is there any list of known inconsistencies or should we go through the
archives before reporting (I've come across a couple in modelling
functions) ?

Thanks

Jonathan
