    Nobody ever said there couldn't be bugs. That some particular platform 
has some particular bug that causes it to violate some particular guarantee 
in some particular standard doesn't change the fact that the standard 
provides the guarantee.

    The issue is whether extern C is guaranteed to work and whether it is 
guaranteed to work without it. My response is based upon what the standards 
say. No implementation details (or bugs) can change what the standards say.
