By the way, one very weird error that I get with SWIG-1.3.31 and your 
python/swig bindings is this:

$ make -C src/optional/python-bindings
swig -python -Wall -Werror \
        -I../../../../src -I../../../../src/engine \
                -I../../../../src/business/business-core \
                -I../../../lib/libqof/qof -I../../../../lib/libqof/qof -o 
gnucash_core.c ../../../../src/optional/python-bindings/gnucash_core.i
../../../../lib/libqof/qof/gnc-numeric.h:243: Error: Syntax error in input(1).
make: *** [gnucash_core.c] Fehler 1

Turns out swig doesn't like the "inline" keyword at all of the places in the 
<gnc-numeric.h> header. If I add the option


to the swig call (i.e. defining inline as an empty macro), swig runs without 
error and the build continues just fine.

No idea whether this is specific to this swig version or what. I just thought 
I'd better send this to the mailing list before I wonder again about this for 
a long time.
