Hi James,

indeed.  You could use the modified rule
        dblocation.texi: ../locate/dblocation.texi
                $(LN_S) ../locate/dblocation.texi $@
where $(LN_S) is 'ln -s' on systems with working symlinks or otherwise one
of 'ln' or 'cp'.  I assume your Makefile.in already contains
        LN_S = @LN_S@
otherwise you should add
        AC_PROG_LN_S
to your configure.ac.

I assume 'make distcheck' will never run on systems without working symlinks
so this should be OK.

Peter
