* origin/topic/seth/fix-compiler-warnings: Fixed problem with PRI macros. PRI macros are currently not working for some reason. Two more small compile time error fixes. Cleaned up the output from running binpac. Added line to expect shift/reduce errors in parse.in Cleaned up g++ warnings. Addition: I fixed a few more warnings I was getting, and tweaked some of the existing changes slightly.
