[cfe-dev] Attempt to install and test the libc++ failing rather catastrophically

Hello,

This bug is fixed in boost 1.46. Just define BOOST_DETAIL_NO_CONTAINER_FWD, and the full headers are included
instead of using forward declarations.

Which really is an oversight in the Standard, and a puzzling one at that: After all, there is a forward header for
<ios>.
