It seems to me that just adding BOOST_NO_EXCEPTIONS isn't enough.  There 
needs to be some documentation that explains:

   *  Why it is there (EmbeddedC++).

   *  That boost libraries are not required to support it.

   *  For boost libraries that do wish to support it, what are they 
supposed to do when they detect an error that is documented as throwing an 
exception?  Do all such errors become undefined behavior in Embedded 
C++?  (I'm sorry - I've never used Embedded C++ so don't know what they do 
about errors which normally would be reported via exception.)
