Interestingly, I just stumbled across a bit of live legacy code that
relies on __gnu_cxx::stdio_filebuf to allow constructing an istream or
ostream from an open FILE*. This does not port to libc++.

What surprised me was that I could find no support for FILE* in
Boost.Iostreams. Writing a streambuf isn't rocket science, but I would
think that this particular use case would be common enough to warrant
library support.

Am I overlooking something?
