Actually, I wonder how you (Richard) and other GCC hackers work with and debug GCC, because it is a real pain in the ass. * All the TREE_ macros don't work. * __extension__ prevents GDB from evaluating many things. * announce_function dumps slow down Emacs (and the shell when working via SSH) when debugging anything related to libstdc++ (or any large testcase). * Hitting auto-completion in GDB means staring at the window for 5-10 minutes until it decides to stop listing stuff. There are quite a few other annoyances, but these are the most common (perhaps I should make a list in the wiki). Cheers, Manuel.
