I was just about to open a bug until I found this one:

https://bugs.gentoo.org/show_bug.cgi?id=407761

It sounds sensible to *not* fix this in boost-1.48, since
gcc-4.7 was hard masked anyway. So, I've unmasked boost-1.49,
instead of using patched 1.48.

But, I've learned how to patch and prepare a private overlay;
so this made my day :-)

Thanks and see ya,
Ezequiel.
