// This file has API thunks that allow shdocvw to load and run on
// multiple versions of NT or Win95. Since this component needs
// to load on the base-level NT 4.0 and Win95, any calls to system
// APIs introduced in later OS versions must be done via GetProcAddress.
//
// Also, any code that may need to access data structures that are
// post-4.0 specific can be added here.
//
// NOTE: this file does *not* use the standard precompiled header,
// so it can set _WIN32_WINNT to a later version.
