Thanks for the patch. However, if a library's libfoo.la file is
mentioned in libbar_LIBADD then this doesn't necessarily mean these
libraries are *statically* linked against each other. Instead, it merely
means "Dear funky libtool, please make sure this libbar is linked
against libfoo, and unfortunatly I have to leave it up to you to decide
whether you do this statically or dynamically." If you're on a platform
where static linking is switched off anyway (like windows/mingw), then
all of these are dynamically linked libraries.

In this particular case, removing these linker flags gives plenty of
"undefined reference to function xyz" errors on windows. Windows is a
particular case here because it doesn't allow any undefined symbol,
whereas other unix linkers are fine with some undefined symbols as long
as they can be resolved at runtime.

Nevertheless these errors are perfectly valid - if the code in libbar
calls a function in libfoo, then libbar must be linked against libfoo.
I've attached an excerpt of the error messages below.

What we *could* do is to reorganize the code split: We could move some
functions out of a libgncmod module into a libgnc library and link
against that instead of the modules.

Regards,

Christian
