Thank you! 

The most recent version I'm aware of is, from November 18, 2016. An earlier version can also be found at (March 30, 2016). The version the test suite uses for its "grub_202_patched" build is at, but since I did some repair to square it against the final grub 2.02 release it's not Ignat's original work.

Any guidance you're willing to offer would be welcome -- I'm hoping to find a good chunk of time this weekend, but it's been ~20 years since I spent the bulk of my time in C, so there's been a bit of skillset atrophy; I'm trying to be slow and cautious. The next step I'm planning on taking is amending the test framework to automate attaching gdb to its test cases; with that done, I expect to be in a place to start walking through the existing code and making notes on how existing behavior squares with the RFC.
