I think this might be possible, but if it meant that not only guile,
but every lib and app that was linked against guile would have to be
packaged two ways, then it's probably not feasible.

Are we talking about guile functions calling c++ functions, or c++
functions calling guile functions here, and are we talking about the
c++ code being accessed via guile loaded (dynamic-link)ed shared
libraries or via direct linking/loadinga?

Also is there a description of the problem available anywhere? i.e. in
the case of exceptions where c code is calling c++ code, is it a
problem if the c++ code throws an exception at all, or only if it
tries to throw one up to the c level.  If the latter, then can the c++
code just be required to have a catch-all "catch" at the top-level in
all of the functions guile will be calling?
