Thank you.  I did find AM_PROG_LN_S and $(LN_S) after my original post 
and that is what I am currently using.

I also saw AC_CONFIG_LINKS but I wasn't sure it would be appropriate for 
what I was trying to do.  I'll have a look at it again.  One other thing 
is that I would like the links to be removed during a 'make clean' step, 
e.g..  Do you know offhand if AC_CONFIG_LINKS will setup any rules to 
remove the links?

Thanks!
