Hey Thanks very much, thats a pretty detailed respone! :) > The gcc documentation is at http://gcc.gnu.org/onlinedocs/ .

But i have been compiling my own version of gcc for ages, so i might as well take a peek into the sources for once. I would love to try and contribute to gcc, but i am a little overwhelmed with how much code there is to get around for such a long standing project. But if there are some code cleanups or something i might take a stab at it. If its possible :) Regards the parser thing yeah thats the way i started implementing it, just its nice to know i have went about doing it the completely wrong way ;). But i am thinking of working a little at a simple assembler and elf linker for now and make a library interface to it, might be a nice way to work with it. Thought not too sure. Anyways thanks for that. Seeing the notes for gcc 4.4.0 seems like a lot of cool work was done! anyways any tips on small contributions for gcc that i might take a stab at would be nice. Thanks -Phil
