What kind of magic does this pragma do?  Do you have a reference?

At the moment, I'm personally not so sure if we go for it if the
problem only happens for a special FreeBSD version of g++.  Adding a
per-compiler pragam for a selected issue may not be harmful itself,
but it will make the code structure more complicated, and the indirect
dependency will probably annoy the current and future developers.
