Dynamic linking with automake and libtool

[James Laird]

Hello.

I have a project that uses automake and libtool to build a library and a
number of tests for it (http://hdf.ncsa.uiuc.edu/HDF5).  The main library
can be either a static or a shared library; when a shared library, it has
a libtool version number.

Since all of the tests include the main library (using LDADD), they all 
depend on that library.  Thus, when the main library is changed, all of 
the tests must be recompiled.

It would be nice if, when the library is configured as a shared library,
the tests only needed to re-link rather than being completely recompiled.  
I can't figure out a way to do this short of editing automake itself.  
Any ideas?

Thanks very much,
   James Laird
