Subject: MSVC: disable warning about constant conditional expressions

The standard headers for Visual Studio 2008 generate a warning about
constant conditional expressions when compiled with exception support
disabled.  This is caused by the _CATCH_ALL macro in xstddef which is
defined thusly:

  #ifdef _HAS_EXCEPTIONS
  #define _CATCH_ALL } catch (...) {
  #else
  #define _CATCH_ALL } if (0) {
  #endif
