FYI,

2.7.4 fails to build on FreeBSD 9.x, that uses by default gcc 4.2.1. I’ve fixed it adding an extra dependency to make force it to require gcc 4.8+. Here is the output:

Interesting. This appears to be the same bug as [1].

Yes. AFAICT that version of gcc is simply buggy, and we are not doing
anything illegal or even particularly exotic. Given how old it is, I'm
not sure it's worth worrying too much about it, but I am happy to work
around it if somebody can figure out how to do so.

I spent some time trying to bisect gcc, but had trouble getting a
working build for a gcc that old.
