 === Problem ===
 When "#include" is executed for the following file, the warning stack is
 destroyed.
 The cause is a misuse of "#pragma warning(default: warning-number-list)".

 File list
  * boost/archive/xml_wiarchive.hpp

  === Impact ===
 When the VisualStudio user uses a specific header, a part of a necessary
 warning is not displayed.

  === Reproduction code ===
 {{{
 #!cpp

 #include <boost/config.hpp>
 #include <boost/exception/all.hpp>
 #pragma warning(error: 4193)

 //boost/archive/xml_wiarchive.hpp
 #pragma warning(pop) // => warning C4193
 #include <boost/archive/xml_wiarchive.hpp>
 #pragma warning(pop) // !!! There is not warning. !!!
 #pragma warning(pop) // !!! There is not warning. !!!

 int main() {
   return 0;
 }
 }}}

  === Patch ===
 {{{
