<pre>We have a case where both "main" and "WinMain" are defined in different .libs
being linked in. We also provide /SUBSYSTEM:WINDOWS on the command-line.
As per spec
(<a href="https://docs.microsoft.com/en-us/cpp/build/reference/subsystem-specify-subsystem">https://docs.microsoft.com/en-us/cpp/build/reference/subsystem-specify-subsystem</a>)
specifying /SUBSYSTEM:CONSOLE shall select "main" or "wmain"; and specifying
/SUBSYSTEM:WINDOWS shall select "WinMain" or "wWinMain", whichever is present.
Given the list in lld\COFF\Driver.cpp, LinkerDriver::findDefaultEntry(),
Config->Subsystem is not taken account, which leads to "main" being selected.
For this exact same case, link.exe selects "WinMain", which follows the
/SUBSYSTEM selector.</pre>
