linking source files from a different directory macro

[Jason Roscoe]

Hi,
I'm new to the mailing list and only have a few days experience working 
with Automake.  I am wondering if a macro already exists that will link 
source files from a different directory into the current one.  For 
example, given the following directory trees:

common/
common/tester.c
common/tester.h

test/
test/Makefile.am

Is there a macro, e.g., AM_SOURCE_SYMLINK( ../common/tester.c ), that 
will create symbolic link(s) to source files residing in a separate 
directory?  Or, if I am looking at this the wrong way, can someone 
suggest an alternate way of achieving this using the Autotools?

test/
test/Makefile.am
test/tester.c  ->  ../common/tester.c

Thanks.
Jason
