Hello,
I'm a user of boost::unordered_map and I always used this container with
exceptions disabled (because I never use them and don't want them enabled
if possible). I never had problems with that, but now with boost 1.50 and
GCC 4.7.1 I get this error while compiling code using unordered_map:

exception handling disabled, use -fexceptions to enable
The strange thing is that compiling the code with CLANG 3.1 and exceptions
explicitly disabled works fine.
There is a way to make it work with exceptions disabled and G++?
Thanks
