 I tried to compile Boost 1_62_0_b1 but got lots of errors in the new Fiber
 library like this:

 I was using commands like:

 {{{
 ./bootstrap.sh --prefix=/my/dest/dir
 ./b2 --layout=tagged variant=release
 }}}

 ...and I saw these problems under both GCC 5.2.1 and Clang 3.6.2 (on
 Ubuntu 15.10, Linux 4.2.0-42-generic, x86_64).
