Thank you. I did find AM_PROG_LN_S and $(LN_S) after my original post and that is what I am currently using.
You can use AC_CONFIG_LINKS([common/tester.c], [test/tester.c])
but can also use out-of-directory sources:

  check_PROGRAMS = foo
  foo_SOURCES = ../common/tester.c ../common/tester.h

and avoid all the symlinks.  Depends on your needs; the latter doesn't work
well with VPATH builds and non-GNU make programs.

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?
