Umm. I think I know the problem here. I have a suspicion that either Fedora or you have changed make to be parallel by default (or you're lying to me and saying you typed 'make' when you actually typed 'make -j4', but I'm pretty sure you wouldn't do that). Because there's no way you'd get this output if you were compiling with make -j1. Indeed, if I revert your commit and then build with make -j4, I see the same error as you. I'll look at how to fix this properly tomorrow.
