Fixed, thanks!

Looks like this https://hg.libsdl.org/SDL/rev/93013728e8a3 doesn't fix it (for whatever reason)

same is true for DUFFS_LOOP4 fix - maybe due to the fact that it is a macro? I have no idea yet. Will investigate a little bit more. Ideas are welcome.

Btw. thanks for taking care that fast.

It works here with gcc 7.2. What version of gcc are you using?

GCC 7.2.0-1 (Debian)
Comment 5 Sam Lantinga 2017-09-11 17:55:03 UTC 
Okay, well feel free to submit a patch that works for you.
