Sure: I made drastic changes in the wrapping process, and it was  
absolutely impossible to make it without breaking things.
Also, I made most of the work on my spare time, and so I had no idea  
about when things may be usable again (if usable at all).
Last point: cableswig has been replaced by swig (the unmodified one)  
and a custom program - igenerator.py - to parse the output of gccxml  
and produce a swig interface. Unfortunately, igenerator.py is written  
in python, so it adds a dependency on python to build java or tcl  
wrappers.

There are still a few problems:
* dependency on python due to igenerator.py. It should be possible to  
recode it in C++, but it's a work with a very low priority on my todo  
list, so it's very unlikely to be done soon. But is it really a problem?
* there is a bug - I think in swig - which makes some methods not be  
wrapped in tcl. See this test failure for example: http://www.cdash.org/CDash/viewTest.php?onlyfailed&buildid=461742
