Does not compile with gcc49 on FreeBSD 9

Any idea on how to solve this?

I has similar error before, but I have not remembered what I did to fix this.
It looks like standard library version related issue:

It turns out it's a problem with the FreeBSD build system.
So for people having trouble, just add this to your Makefile:

USE_GCC=    4.9

Sorry for the noise :)
