Bug 23698 – ImportC: __stdcall is not documented as supported MSVC/DMC extensions

__stdcall is a Microsoft and Digital Mars C extension.

(In reply to Walter Bright from comment #1) > __stdcall is a Microsoft and Digital Mars C extension. Then it needs documenting under both MSVC and/or DMC sections of the importC page. https://dlang.org/spec/importc.html#visualc-extensions
