With modern gcc (read: 4.3 and higher), you can use the following:

-----------snip--------- 
 #if defined(__GNUC__)
    #pragma GCC diagnostic ignored "-Wdeprecated-declarations"
#endif

void foo(int bar
{
}

+#if defined(__GNUC__)
+    #pragma GCC diagnostic warning "-Wdeprecated-declarations"
+#endif

~~~~~~~~~~~

That doesn't quite work, how do you know that the user 
wants -Wdeprecated-declarations to be set to "warning" after the include? 
Could be the user has disabled that one on the command line, in which case 
if we turn it back on, that's as annoying for the end user as warnings from 
Boost!  There was a time when some MSVC std lib headers behaved like that, 
and believe me it was *seriously* annoying :-(
