You could do what Google Protocol Buffers does and determine which

hash map to

use at configure time. It works with g++ 3.4.x all the way up to

4.4.x. See

the m4 file at:

IMHO this seems to be a bit of overkill, and my preferred option would
be just to specify that >=boost-1.36 was necessary. However I know that
may not be an option for everyone so I'll let the OSL core developers
chime in. What's the story guys?

I'll note that using hash_map *does* compile with g++-4.4.1, but not
without warnings (and hence doesn't compile when using -Werror which is
turned on by default in the build scripts).

Protocol Buffers has a new BSD license so this could be copied

straight from

them.

The M4 would have to be converted to cmake, but it's good to see all the
potential places which hash_map may reside. Gosh there's a lot!
