[boost] is_convertible for intel 7.1 and 8.0

From: David Abrahams (dave_at_[hidden])

The following line

      || (defined(__EDG_VERSION__) && (__EDG_VERSION__ >= 245) && (!defined(BOOST_INTEL) || BOOST_INTEL >= 700)) \

was added in revision 1.20:

  date: 2003/07/31 01:16:32;  author: beman_dawes;  state: Exp;  lines: +1 -1
  improve Intel 7.0/01 performance

But unless I change it to:

      || (defined(__EDG_VERSION__) && (__EDG_VERSION__ >= 245) && !defined(BOOST_INTEL))  \

is_convertible_test fails to compile on windows with Intel 7.1 (with /Qvc7.1)
and Intel 8.0 (with /Qms0).

Do we need a different test?  Was this added for intel/Linux?
