For some reason I don't want to really understand, the following
happens with gnu as.

After an exhaustive search and experimentation at 11pm, I discovered that
putting them in parentheses fixes the compilation.
Ed pointed out that I could likely fix this in a bunch of other
locations but I'd rather leave these alone until other options
are enabled.
Tested:
* gcc-6, amd64
