While building 1.68.0 beta 1 on x86_64 linux cross-compiling to Windows 64 bits with minw-w64 + g++ 8.2.0, I get this warning:

@Lastique looks like this issue belongs to Boost.WinAPI My guess is that _OVERLAPPED requires two BOOST_WINAPI_DETAIL_EXTENSION

See if https://github.com/boostorg/winapi/commit/fee1bec7f97c24d082ea0b1300aba83c3899484e fixes the problem.
