Hi Steve,

I indeed broke the build for recent GCCs in

Use range-based for loop in remote_add_target_side_condition
8362122330c97c8c4a15da4e7ba8aa29f0c11157

and fixed it right after with

Remove struct keyword from range-based for loop
d538e36decd5628c084dbd5a7de13719b8b92121

I am still using an ancient 4.8 GCC, so I did not see it, but Sergio's 
buildbot informed me within a few minutes.  Let's just pretend it was a 
test for the bot :).  Sorry about the inconvenience and thanks for being 
alert.
