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
--------------------------------------------------------

do disable warnings locally.

If you want find out which options controls this warning, use 

     <toolset>gcc:<cxxflags>-fdiagnostics-show-option

for current gcc.

This should work.
Maybe we should add "-fdiagnostics-show-option" to gcc.jam for gcc 
greater 4.3...

Yours,
