Thanks for the info.
It's weird that this is just showing up for you, and I assume works everywhere else. How are you invoking the compiler, via make, or something else?
And, what's the gcc command line look like when this specific file fails?
I grepped the source code, and didn't see anywhere else where we import something this way, so maybe that's a reason to change it.
As for the "./" think: maybe using it would be a better hint as to what's going on.
But I'd like to hear from other core devs and get their opinion on any change, first.
