This is in already a patch in my archive:

tla revisions -s g-wrap--rotty--0.2
patch-1
    Add runtime library, ffi support
...

My g-wrap-runtime.c has 774 lines...

Hmm, I'm not exactly totally clear what I intended here, too ;-) My
idea was to get rid of the second shared libs per wrapset
(e.g. libgwrap-glib.la). But don't I think that is that important
anymore. Anyhow, if it is possible to link against a .la that is used
used as the C part of the guile module generated, we may as well link
e.g.  g-wrap-glib.c into libgw-glib.la instead of libgwrap-glib.la and
get rid of the latter. Hope this makes this a bit clearer. A related
note: libtool (1.5 at least) apparently complains about the mix of
-module and direct linking:

*** Warning: Linking the executable test-link-gw-wct against the loadable 
module*** libgw-wct.so is not portable!

This may indicate that direct linking is not supported for modules,
which would make the separate shlib necessary in cases where the
functions in there are used by more than one wrapset.

Cheers, Andy
