After I landed the patch for bug 557566 today, vlad reported this build failure in his local build:
{
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\typeinfo(157) : error C2220: warning treated as error - no 'object' file generated
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\INCLUDE\typeinfo(157) : warning C4275: non dll-interface class 'stdext::exception' used as base for dll-interface class 'std::bad_cast'

}

Note that TryServer & m-c tinderboxen don't hit this -- not sure what's different between them vs. vlad's setup that make him affected & them unaffected.

In any case, assuming we don't care about this warning, we can should just disable it in configure.in

Attachment: fix: disable warning?

Assuming we don't care about this warning[1], this will disable it.

[1] haven't yet really investigated what the warning means or whether we care about it
