[section:no_exceptions_support Header <boost/core/no_exceptions_support.hpp>]

Example of use:

``
void foo() {
  BOOST_TRY {
    ...
  } BOOST_CATCH(const std::bad_alloc&) {
      ...
      BOOST_RETHROW
  } BOOST_CATCH(const std::exception& e) {
      ...
  }
  BOOST_CATCH_END
}
``

With exception support enabled it will expand into:

``
void foo() {
  { try {
    ...
  } catch (const std::bad_alloc&) {
      ...
      throw;
  } catch (const std::exception& e) {
      ...
  }
  }
}
``

With exception support disabled it will expand into:

``
void foo() {
  { if(true) {
    ...
  } else if (false) {
      ...
  } else if (false)  {
      ...
  }
  }
}
``
