hm, why does this patch change the Makefile?

i've skipped this hunk, it does not appear to be connected to the
commit.

Probably because he wanted to debug things and O6 generates crappy gdb
experience.. and then it slipped into the diff

Yeah, that's exactly what happened. Damn, I thought I put the -O6 back.
This patch, I originally just did the '-', and thought. Hmm, it is
trivial to do the '+'. So I added it and did a "git commit -a --amend",
forgetting that I modified the Makefile.

This hunk can be ignored.

Thanks!
