I want to detect whether or not the -no_exception compile time flag

Yes, it does.
Hmmm - I've written a small test which seems to show that it doesn't.
#include 
#include <exception>
int main(int, char *[]){
     #ifdef BOOST_NO_EXCEPTIONS
     throw std::exception();
     #endif
}
I'm still investigating this.
Looks like I setup my test wrong.  Should be

#include 
#include <exception>

int main(int, char *[]){
      #ifndef BOOST_NO_EXCEPTIONS
      throw std::exception();
      #endif
}

This does seem to respond to the command line switch -fno-exceptions as 
I would hope.  So I guess my question is answered.

Thanks to everyone for their constructive comments and suggestions.
