        <pre>MSVC always instantiates "extern inline" functions.  Furthermore, prior to the
addition of /Zc:inline, it would never discard the separate instantiation of
the inline function, so the symbol would always be available for use from
another translation unit.

This is actually used by _AtlInitializeCriticalSectionEx.  The intention
appears to be that the user of the library should include this header, and then
the ATL will pick up the definition from the user's object files.

I believe this was the cause of link errors when building nacl64.exe in
Chromium.</pre>
