ok - ./autogen.sh does it (sorry I'm not that familiar with the autotools
yet) - build seems to be ok now. A quick check shows that 1.0rc1 has a
problem though with some valid XML (xmlfw atleast conciders it valid) -
for simple files it works as expected:

 while 0.4 gives me the expected

 a bt in gdb of the problem shows:

 It seems to be only a size issue - with a small xml file all is fine
(same file basically, just removed some child elements). Should I send the
file causing the problem (though I doubt it is related to the content any
way - looks like some buffer overflow to me) ?

thx!
