Hrr, Executors are newer than version 4 and even if they can be 
considered as an extension, the async()/then() interface change and some 
compilers don't support the Executor interface. This is why I didn't 
defined the macro for version 4. Sorry for the confusion.

I'll add it as soon as the interface is stable (maybe in 
BOOST_THREAD_VERSION 5) . Unfortunately it is not yet the case.

Don't worry for the PR. I will fix it myself.

Thanks for all.
