Many classes use the BSONCXX_API macro to export symbols related to its members.
This pattern does not account for the required BSONCXX_CALL macro on function symbols to support users on Windows building with a different default calling convention than __cdecl (e.g. __stdcall, __fastcall, etc.). This is outlined in CXX-81.
Executables under the examples subdirectory are compiled with /Gv to test for the absence of __cdecl in the API. However, the API coverage of examples is very small compared to the library test suites: see CXX-3092. Attempting to increasing API coverage in examples as part of CXX-3082 triggered build failures (as intended) due to missing __cdecl.
Audit the set of exported symbols in the current C++ Driver API and ensure functions are declared with __cdecl as required.
