C4275 compile warning

[Angus]

I am getting this error:

asn-buf.h(133) : warning C4275: non dll-interface class
'std::basic_streambuf<char,struct std::char_traits<char> >'
used as base for dll-interface class 'SNACC::AsnRvsBuf'
asn-buf.h(132) : see declaration of 'AsnRvsBuf'

The line causing the problem is:
class __declspec(dllexport) AsnRvsBuf : public std::streambuf

What is the problem and how do I resolve?

Ask on a newsgroup dedicated to your platform. DLLs are
platform-specific and off-topic here (see
http://www.parashift.com/c++-faq-lite/how-to-post.html#faq-5.9).

Use a platform with real shared libraries.

There is no problem to resolve. Disable the warning. Visual Studio
often goes ape shit over template instantiations in DLL projects and
spews a bunch of bogus warnings like the above.
