You might have figured this out already but just in case something is
1. How to check out our sources using svn and git is described at
https://gcc.gnu.org/svn.html and https://gcc.gnu.org/wiki/GitMirror
2. perhaps more importantly, how to configure, build and test GCC is
described in steps linked from https://gcc.gnu.org/install/ (look
for --disable-bootstrap, among other things).
If you have any specific question regarding any of these steps, feel
free to ask on the mailing list or the IRC.
