How to get AST for C source in plugin?

Hi,
I'm trying to do some static analysis of C source using GCC 4.5 and my
plugin.
I've tried registering my plugin for PLUGIN_FINISH_UNIT event. My plugin
gets called, but I couldn't find a way to access AST - nothing is passed
to my plugin as parameter. Maybe there is some GCC's global variable
that contains AST I can use?
Alternatively I've tried Kenji Koyanagi's patch
(http://gcc.gnu.org/ml/gcc/2009-03/msg00136.html) and it worked just
fine, but I don't know whether this patch is going to be accepted in GCC
4.5 codeline, which can be a show-stopper for me, because I want my
plugin to work with standard compiler. Are there plans to add
PLUGIN_C_PRE_GENERICIZE event to GCC plugin infrastructure?
Are there any other ways to get AST for the whole translation unit or
separate functions in my plugin?
Regards,
Ilya
