Description:
Here are some fixes to get OSL to compile with gcc-4.4.2. Some of these
fixes I shamelessly lifted from Chris.F's patch from a while back. It's
mostly pretty straightforward.

I've added support for unordered_map/sets if the compiler is new enough.
I'm not sure if this is the way we want to proceed because it's rather
verbose/ugly (should I use a #define instead?). Maybe once we upgrade
to something more recent than our archaic compiler and boost library
then we can clean this up properly?

LGTM2. Good to see the patch I posted a while back wasn't too moldy
to be slightly helpful :)
