OK. This was added by me in commit
7aaa9bee2e6009c6c00fa2a356b8f014999e9a54. There was no clear
explanation of the problem, it was just "it doesn't build, and nobody
cares". And it was 3 years ago, so there are high chances that the
problem has been fixed either in uClibc or in Boost. So let's try to
remove this dependency indeed. Waiting for your patch!

(BTW, you still haven't joined IRC! :-))

Thanks!
