Applied.   Thanks.

Now I'm curious.  What did you do to notice this?  

I don't really understand how it works, but when I say:

[src/gnome-utils/test/]$  /bin/sh ../../../libtool --tag=CC --mode=link \
  gcc -g -o test-gnc-dialog  test-gnc-dialog.o -Wl,--export-dynamic \
  ../../../src/gnome-utils/libgncmod-gnome-utils.la

It links with src/engine/.libs/libgncmod-engine.so even without this
patch.  (and many other .so libraries that aren't referenced directly.)

I presume this is either because libgncmod-gnome-utils.la lists
src/engine/libgncmod-engine.la in the "dependency_libs" variable, or
because it's in the "relink_command" variable.

Either way, I want to learn: when can I count on this libtool magic
and when can't I?
